The second annual ‘National Unfriend Day,’ the annual holiday started by Jimmy Kimmel, is tomorrow. It’s the day when you have to go on Facebook and unfriend people who really aren’t your friends.

Everyone is going to participate, even the Peanuts gang, as we saw in this funny animated short from last night’s ‘Jimmy Kimmel Live.’

Check out what is sure to be a new holiday classic below.
