Jimmy Fallon breaks into song at Vancouver's Le Crocodile

First Jimmy Fallon upstaged Paul McCartney in Vancouver by joining him onstage for "I Saw Her Standing There".

Then he upstaged a dinner at Alsatian fine dining restaurant Le Crocodile by singing R. Kelly's "Ignition (Remix)" as part of an a cappella quartet.

Watch out, Vancouverites: Fallon may soon be crashing your next karaoke party.
