The sweaters that Bill Cosby wore on The Cosby Show are legendary. There are Tumblrs dedicated to them, songs written about them, and days dedicated to themJanuary 20 marks National Bill Cosby Sweater day. Even the man responsible for these wild knits happens to be one of the coolest guys in the world.

Now Bill Cosby himself—via his personal website—wants you to vote which of his colorful knits is your favorite. It’s easy to forget about every sweater when there are over 200 episodes of the classic show, but everything is conveniently broken down on the site, NCAA tournament bracket style. There are the argyles, the cashmeres, the pullovers, and the cardigans. There's only one day and 23 hours left to vote, so get on it now. Plus, a vote enters you to win an autographed copy of one of Bill Cosby’s books. Check some of our favorites above and visit the Bill Cosby website to place your picks.
