What set does this minifigure head come from?

Question

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.

Answer 1

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.
