Marv Albert Dangerous Bite
Marv Albert is the only Celebrity Bite to have actually bitten another person without their consent. Seriously, he bit a woman, faced criminal charges, then plead guilty after DNA tests matched the bite marks to his teeth. His resume should read, "Marv Albert. I bit a woman once. I'm also a sportscaster". You're never living that one down, Marv.
On a side-note, during my research I found Mr Albert interviewing President Obama. Like, interviewing him from only a few feet away. Did the Secret Service, and most importantly President Obama, know that this man has a bite history? Three feet away from the most powerful man on the planet...chew on that one for awhile.
