It's not easy being a comedy actor.
Sure, there is hilarious material to work with, fun co-stars, and getting paid to do what you love.
But there is just one wrinkle here: it's hard not to laugh during hilarious scenes!

Before the sentence is finished, Rainn turns his head away from the camera while laughing!

As a result, Rob couldn't help but smile at the nonsensical blabber coming out of Charlie’s mouth.
