Jimmy Fallon always has the best games and gags, but this one is got to be near the top for me. I've always though it would be fun to take an established band and put them out in public and see if anyone knows who they are, he did with U2.

Here is the footage of the band in disguise doing a U2 song and everyone looks like they don't care, but then they take off the disguises and do a U2 song and everyone goes nuts!
