Zach Galifiankis made an entertaining appearance on "Late Night With Jimmy Fallon" last night, giving both Fallon and the audience two surprises. First, while discussing his recent appearance on Bill Maher's show where he appeared to smoke a joint, he took off a wig to reveal a buzzcut underneath. Then later on, he appeared in a sketch with Fallon using prosthetic arms that was nothing short of hilarious.
In the first clip below, Galifianakis implies to Fallon that the joint he smoked on "Real Time" was "smoke and mirrors" as he pulls a wig off of his head to reveal the nearly-bald haircut. Fallon immediately begins tugging on Galifianakis's beard to see if it's real (it is) and cracks up at the surprise.
Later on, Fallon reprised a really funny sketch he once did with Will Ferrell on the show where they reenact a "Canadian soap opera" and use prosthetic arms to play pool and pour beer into mugs.
