What set does this minifigure head come from? I came across this picture:



I think the body is from The LEGO Movie Pajamas Emmet polybag, but have no idea where the head is from.
It's from Fairground Mixer (10244).

Also, the rest can be had way cheaper than Pyjamas Emmet polybag in the form of Sleepyhead from Collectible Minifig series 6.
