Actors breaking character during bloopers are some of the funniest stuff we're lucky the networks allow us to see! In this one, Julia Louis-Dreyfus (Elaine Benes) can't keep it together while filming the 'Festivus' episode of Seinfeld.

It's rumored that the dinner scene alone took SIX HOURS to film because Louis-Dreyfus kept laughing. She was mainly laughing at Larry Charles, Seinfeld producer who randomly made cameos as a random weirdo. His take on 'I think you're a fox' is what kept cracking Elaine, and the rest of the crew up!
