"Tonight Show" host Jimmy Fallon kicked off Wednesday night's show with some presidential campaign humor, but he told the audience he "might have pulled something" after a particularly tricky Jeb Bush joke.

Fallon tagged back into the action in time to offer up a treat with another Jay — or rather J.Lo.

Jennifer Lopez teamed up with the funnyman for a hilarious take on his recurring tween girl bit "Ew!"
