Jump up, jump up and get down to this hilarious lip sync battle.
Fallon kicked off with House of Pain’s hit “Jump Around,” before O’Neal got some surprise help from rapper Pitbull in performing Bobby Brown’s “My Prerogative.”
After Fallon’s very unique take on the “Beauty and the Beast” theme, the adversaries then teamed up for a special version of the Elton John and Kiki Dee duet “Don’t Go Breaking My Heart.”
There was only one winner, though. Warning: Shaq’s moves cannot be unseen.
