Watch Larry David Giggle His Way Through This SNL Blooper Reel

Larry David hosted Saturday Night Live this weekend, where he reprised his Bernie Sanders impression for a delightful Curb Your Enthusiasm spoof.

David also starred in a less topical but still entertaining sketch called “FBI Simulator” as Kevin Roberts, an eccentric man with a penchant for doughnuts and neon orange suits. He pulled off the sketch pretty well, but as you’ll see from the outtakes real SNL just released, he had a really tough time with it during rehearsals.

And by really tough time, we just mean he could not stop giggling.

Vanity Fair has a theory about why this bizarre sketch aired so early in the show, when it feels like it would belong later in the night: Lorne Michaels was really hoping David would break character.
