Larry's Club
Beaver is sworn into 'the Bloody Five' which is a secret club founded by Harold. Larry gets really jealous when he is told that he is not allowed to join, so he starts his own club called 'the Fiends'. Beaver then disowns the Bloody Five and joins the Fiends, only to find out that he and Larry are the only ones in the group.
