Daniel Radcliffe Commands Jimmy Fallon to Do the "Gangnam Style" Dance

Jimmy Fallon has some serious moves! The Tonight Show host was forced to do the "Gangnam Style" dance during his show on Tuesday night after his guest Daniel Radcliffe commanded him to do it. The actor, who played a hilarious game of Water War with Jimmy earlier in the show, made a surprise appearance at the end of the host's monologue. After starting his bit with a joke, saying, "South Korea is building a giant monument to the song 'Gangnam Style,' which will feature two overlapping wrists, a signature move of the 'Gangnam Style' dance," audience members then pressured Jimmy to do it. Watch the funny clip above, then check out the trailer for Daniel's new movie, Victor Frankenstein.
