'National UnFriend Day' calls for trimming down of Facebook friends list

Tuesday is 'National UnFriend Day' - an annual social media holiday that encourages people to trim down their Facebook friends list.

Jimmy Kimmel came up with the idea as a joke several years back.

As examples, Kimmel says the people you should unfriend are those who give away endings to TV shows, those who over-share, and those who ask questions that are easily answered online.
