You'd forget sometimes that SNL stands for Saturday Night Live - meaning that it's taped live and, sure enough, sometimes people either crack from the jokes or just plain mess up in the process.

Louis CK hosted last night's show and was involved in a few sketches, one of which involved he and Kate McKinnon pretending to be museum actors in a tenement museum. That's the setup, but where the humour really comes from is Louis and Kate trying to desperately to keep a straight face.

This isn't the first time Kate McKinnon's cracked, having pretty much ruined - well, not ruined but made everyone laugh - during a sketch with Ryan Gosling about aliens.

Here's the sketch from the last night.

Believe it or not, the fact that Louis CK and Kate McKinnon can't keep it together is funnier than the actual conceit of the sketch in the first place. It seems like Louis isn't much suited to sketch comedy, but that's OK - his Netflix special is one of the funniest things on the streaming service right now.
