National UnFriend Day Gets Charlie Brown Kimmel Kartoon (VIDEO)

Jimmy Kimmel made headlines last year when he declared November 17 to be National UnFriend Day, a day when Facebook users the world over should cleanse their friends lists of people who aren't real friends.

Relentless in the effort to establish the holiday's legitimacy, on Tuesday Kimmel debuted his newest Kartoon, "It's National UnFriend Day Charlie Brown." As the host explained, "No holiday is a real holiday unless it has its own 'Peanuts' special."

Well, consider National UnFriend Day officially bona fide. So, how will you be celebrating on Thursday?
