Since the '70s people have used 420 as a term to celebrate marijuana and no one can agree why. Is it because 420 is the police code for marijuana? Is it because there are 420 chemicals in marijuana? Is it because 420 Mars Bar wrappers were found in Jerry Garcia's belly button when he died?

Who cares! UCBT thinks 420 is all about getting high and laughing so we've compiled some of the funniest pot lovers around for 420 Funny: A Very Pot Friendly Variety Show. With stand-up, sketch, short films and just plain stoney things.
