In case you were wondering what it takes to make consummate performer Zach Galifianakis lose it in the middle of a bit, the answer is: a body-dysmorphia medication that made him grow insane eyebrows. It’s really amazing to see a man who once perfectly lip-synced “Tomorrow” while dressed as Little Orphan Annie suddenly start giggling at his own joke. And he hadn’t even gotten to “candy ass of the penis!” The funniest joke of all! But now, to pull off this bit, Galifianakis has to commit to those eyebrows, and to laughing at his own jokes for as long as he’s doing the late-night circuit to promote Baskets. I don’t make the rules. This is just how this works. Oh, and the rainbow shaft, too. Gotta get those markers. Gotta get to work.
