When celebrities do stand-up, the results aren't always hilarious. But more often than not, their sets reveal the actor, politician or socialite's sense of humor about themselves more than their actual sense of humor.
On last night's "Late Night," Jimmy Fallon offered yet another non-comedian a turn at the mic: "Harry Potter" star Daniel Radcliffe. Although his set is pretty brief (and we do mean brief) we like how he didn't try to be a hot shot right away. Let's just say, he starts things off with "This is going to be terrible."
Watch Radcliffe's comedy "debut" below.
