Not many people know this, but there is a sports mascot hall of fame out there honoring the best in those crazy characters that wander the sidelines. The hall is open to mascots from all sports, both college and professional. The Mascot Hall of Fame was established in 2005 and since then only one pro football mascot has been inducted, that would be “K.C. Wolf”, the official mascot of the Kansas City Chiefs.
The Mascot Hall of Fame is an online only hall of fame that was founded by David Raymond who just happened to be the original Phillie Phanatic, debuting for the Philadelphia Phillies in 1978. The main requirement to be eligible for the Mascot Hall of Fame is that the mascot has to have been around for at least ten years.
