Cory Monteith brought his adorable self to chat with Ellen DeGeneres for Friday’s show, and the dreamboat got a chance to show off his prankster side.

The 28-year-old Canadian actor stopped by and talked about everything from going the the Grammys from his teenage obsession with the John Travolta’s film Broken Arrow, (he saw it 23 times!)

Ellen also sent Cory to play a prank on an unsuspecting yoga instructor and (natch) hilarity ensued. Check out the full video, after the jump!

The episode doesn’t air until Friday afternoon, but if you’re like us, you’ll be tuning in again.
