When you're bored, there's nothing more fun than taking the belt off your robe and playing "monkey" while trying to land in the ER again.
Note how Jackson just keeps playing his game, completely unfazed by Clay.
When that gets old, make a swing out of it.
When you get bored playing monkey and swing, just pull your pajama bottoms up over your shoulders and you have a brand new game.
I swear, I have no idea where he comes up with this stuff.
