question: Why does it say "DO NOT PUSH" on the back of dumptrucks?
comment: Quite clearly because you are not supposed to push it. Seriously though, it depends; that is, the trucks I've seen typically have it written on the metal bars on the back which presumably would give out under the force of another truck. There could also be risk to the hydraulics should you over exert energy (push) on them. Generally speaking, the trucks are not designed to take any hit, no matter how slowly applied, to the back of their frame. Lots of moving parts in pressed metal that would get bent out of shape about being bent out of shape.
passages: PUSH's Registered Trademark was originally applied for in 1996, then was renewed by Deutsch's company "Real Simple Ideas, LLC."
  
  On February 10, 2014, despite a social media campaign particularly on Twitter using the hashtag "#savePUSH", Push the Talking Trash Can was retired at Walt Disney World.

   Mr. Yuk was first introduced in Pittsburgh in 1971, and over the next few years, Mr. Yuk stickers gained nationwide The stickers usually contain phone numbers of poison control centers that may give guidance if poisoning has occurred or is suspected. Usually, stickers may carry a national toll-free number ("1-800-222-1222" in the United States). In some areas, local poison control centers and children's hospitals issue stickers with local numbers, under license. Such an example is in Pittsburgh, where the telephone number for the Poison Control Center is 681-6669.

  The episode received mixed reviews.
   On his radio show, Rush Limbaugh offered a slightly different formulation of the slogan: "Keep your hands off my tea bag, Mr. President", alluding to the recent use of the phrase "tea bag" in reference to the Tea Party Movement. In another variation, news anchor Brian Williams said on the "Late Show with David Letterman", "I always get it at [Los Angeles International Airport]. I get nailed. They go, they go right in. This new thing, they go right after Dave and the twins."
   The lack of clear definition of OB marker resulted in mixed responses by the police and the government during the "White Elephant" incidents at Buangkok MRT Station in 2005. An undisclosed person posted a series of cut-outs of elephants to criticise the delayed opening of the mass transit station. This led to a police investigation. Although the person was later let off with a stern warning, Deputy Prime Minister Wong Kan Seng commented that "we cannot apply the law to some and turn a blind eye to others. If we do, then the law becomes the real white elephant."
   a) A person who owns, possesses or controls a dog, cat or other animal shall not permit the animal to commit a nuisance on a sidewalk of any public place, on a floor, wall, stairway or roof of any public or private premises used in common by the public, or on a fence, wall or stairway of a building abutting on a public .

   BULLET::::- An episode of "SpongeBob SquarePants", "Banned in Bikini Bottom", uses the phrases "you are a nuisance to my community", "…said this ninety times", and "cops, I need you!" In another episode, "Porous Pockets", SpongeBob says, "and I said, go ahead, let’s do it right now! I got too much hair, anyways." referring to what Raymond claims he told the police. In "The Algae's Always Greener", Mr. Krabs says to Plankton "you're just a dirty little man". In episode 17 of Season 5, Spongehenge Patrick says "I wanna watch something decent, like..." which may be a reference to the recording when Raymond and Peter are arguing about what to watch on TV, and Raymond says that exact line.
   In 2018, the company was criticised for erecting a large "Bollocks to Brexit" sign on top of their premises in Waterloo. Mullins defended the use of the sign, referring to the Sex Pistols' 1977 album "Never Mind the Bollocks, Here's the Sex Pistols" as precedent for being able to legally display the word in public.

   The word "dumpster", first used commercially in 1936, came from the Dempster-Dumpster system of mechanically loading the contents of standardized containers onto garbage trucks, which was patented by Dempster Brothers in 1935. The containers were called "Dumpsters", a blending of the company's name with the word "dump". The Dempster Dumpmaster, which became the first successful front-loading garbage truck that used this system, popularized the word.
  
  The word "dumpster" has had at least three trademarks associated with it by Dempster Brothers, but today it is often used as a genericized trademark. All three trademarks have since either been expired or cancelled.
   Don't touch my junk
  
  "Don't touch my junk" is a phrase that became popular in the United States in 2010 as a criticism of Transportation Security Administration (TSA) patdowns. The word "junk" is American English slang for a man's genitals. The phrase refers to the offense many people took to the November 2010 decision by TSA to begin full body patdowns of airline passengers in the U.S. who refused to go through a full body scanner.
  
  Section::::Origin of the phrase.
   A recycling bin version of Push (named Pipa) can be found at Disney's Animal Kingdom in the Rafiki's Planet Watch area. Pipa means "container" in Swahili, fitting the Animal Kingdom theme. The bin’s regular steel liner hides the radio control system and plastic trash bag should a guest peer inside.
  
  Since 1958 the Dutch theme park De Efteling in Kaatsheuvel has similar recycling bins named and designed after the fairy tale character of Hollow Bulging Gijs ("Holle Bolle Gijs"), a young boy that always shouts for 'more food', and sucks up garbage thrown into his mouth.
   When the Macintosh was introduced in 1984, the keyboard had a single command key with a Looped square symbol (⌘, U+2318), because Steve Jobs said that showing the Apple logo throughout the menus as a keyboard shortcut was "taking [it] in vain". Thus, the ⌘ symbol appears in the Macintosh menus as the primary modifier key symbol. The original Macintosh also had an Option key which was used primarily for entering extended characters.
   While flyposting is commonplace, it is often viewed as a nuisance by landlords and they can take civil action to protect their property rights. A particularly noteworthy incident of this type occurred in Boston, Massachusetts. In the case of the 2007 Boston Mooninite Scare, advertisers had placed electronic signboards without notifying local authorities, prompting a costly reaction by the Boston Police Bomb Squad when the signs were mistaken for bombs.

   The phrase was inadvertently coined in 2010 by passenger John Tyner, an Oceanside, California computer programmer who released an audio recording from San Diego International Airport in which he told TSA agents: "If you touch my junk, I'm going to have you arrested." Tyner had initially chosen to undergo a pat-down rather than going through a full-body scan machine because of health concerns and the fact that he viewed the machines as a threat to privacy. The TSA refused to allow him to pass without this intimate search and so he declined to travel and got a refund on his ticket. An official then demanded that he submit to a search regardless. He declined and was threatened with prosecution, as well as a fine of $10,000.
   Both in Germany and in most of the European states to which IWL might have hoped to export scooters, trolls are known from Norse mythology and Scandinavian folklore as beings that are in many cases slow-witted, in some cases ugly, seldom friendly to humans and in a few cases inclined to kill and eat people. Why any vehicle maker would choose to name one of its models after such creatures is not clear.
   The invention is credited to Brooke Miller, of Anaheim, California. The design she patented is a metal bin with a rake-like edge attached to a wooden stick. It also includes a rake-like device to scoop the poop into the scooper and a hatch that can be attached to a garbage bag that fits onto the base. The generic term "pooper-scooper" has been included in dictionaries since the early 1970s.

  In 2006, Mattel came under fire from nurses for a new single called "Nurse Quacktitioner". Thousands of nurses complained to Mattel about the reference to "quacks" -- in medicine a common expression for a medical practitioner who is a fraud. Mattel replied that the figure was a duck, and that ducks "quack". The figure was withdrawn from the market.

   Dumpster
  
  A dumpster is a type of movable waste container designed to be brought and taken away by a special collection vehicle, or to a bin that a specially designed garbage truck lifts, empties into its hopper, and lowers, on the spot. The word is a generic trademark of "Dumpster", an American brand name for a specific design. Generic usage of "skip" or "skip bin" is common in the UK and Australia, as Dumpster is neither an established nor well known brand in those countries.
