Jimmy Fallon seems like great fun.
Just look at him here, talking to Irish actress Saoirse Ronan about the nature of a pub lock-in, or competing in an intense lip-sync battle with Tom Cruise.
He’s a consummate entertainer, and he seems to be one of those people that is always ready to perform.
He did just the recently at a Vancouver restaurant, when himself and his friends treated the diners to an impromptu a-cappella rendition of the R Kelly classic, Ignition.
The performance was in his signature barbershop style, which he uses often on his late night talk show.
