Vince Vaughn was back on the "Tonight Show" Friday, putting his movie knowledge - or lack thereof - to the test.
The "Wedding Crashers" star was on the show for the second consecutive night, and played "5 Second Summaries" with host Jimmy Fallon. The game gives one player five seconds (then three, then one) to describe a popular movie well enough for the other player to guess.
How would you have done?
