I'm not the most avid viewer of Adventure Time, but there was an episode where Jake's imagination went out of control and brought things to life that put them in danger, and they had to find a way to shut it off.
At one point Jake accidentally imagines a troll at the end of a bridge that impedes their progress. Finn turns to Jake and gives him an annoyed look, which causes Jake to blush, shrug, and let out a sheepish laugh like "buh hah hoh hu." I thought it was the funniest shit ever.
