SMBC can be pretty hit or miss, (especially in its somewhat cursory treatment of views of economists) but I do like that second Superman one.

I'm voting to close this question as off-topic because it is not about economic theory and applications. It degrades the site, and becomes a broken window that attracts other and worse damage. The very creation of a "fun" tag - like the creation of this question - becomes a magnet for all sorts of junk

Maybe one way to make this question less contentious (as suggested by Alecos in the above-linked meta discussion) would be to ask people to write a pedagogical justification for their answer: How can the jokes people post help to make important ideas in economics more intuitive and entertaining?

# Jokes in Economics; Challenging Assumptions in the Dismal Science

(Asked by: username_0 on 2016-03-22)

We've delved into questions about the history of economics. We've pondered what the most important equations in economics are. But in every science, academic culture inevitably forms a special set of ideas that further our understanding of the most fundamental ideas we use in our work: jokes.

Jokes are only funny if they set you up to have a false assumption about the material at hand, and then subvert it. In this way, jokes can be used to reveal underlying assumptions we economists might take about the world that are very well absurd, but important nonetheless to moving towards more sophisticated models. Even within mainstream economic schools, ideas like using cardinal vs. ordinal utility, or utilitarianism itself can be contentious. John Rawls's veil of ignorance or Nozick's more libertarian epistemology? Are sticky wages *really* realistic?

What are some jokes you have encountered that would be useful for addressing an underlying assumption of an economic theory, or economics itself?

(Any further recommendations for improving this question are appreciated. It can even be a community question if that would be best.)

A physicist a chemist and an economist are stranded in a deserted island after a wreckage. They have managed to salvage a case of canned food, but they have nothing to open the cans, and the island is a true paradise -meaning, all sand and beaches and soft bushes -but no stones, nothing hard.  
The physicist and the chemist try to put their scientific knowledge to work by conjuring forces of nature, gravity, pressure, materials science, inorganic chemistry etc, but they can't make them to work in their favor, they lack the necessary infrastructure to do it.

Meanhwile, the economist is laying on the side, enjoying the sun and smiling, a bit cockily.

-Why do you smile? - Ask the scientists, angry and frustrated

-Because I have the solution - replies the economist

-Which is? - challenge the scientists

The economist looks up, with a trace of pity in his eyes, gets up and says very confidently:

> **"Assume that we have a can opener".**
