After a tooth extraction, Kevin develops a bizarre snakelike fang in the back of his mouth. Percy meanwhile has been arrested for saying "BOMB" at the airport. He cops a deal to become a snitch on the Quebec Mafia, but makes everything up, and uses his newfound stoolie immunity to drive on sidewalks and act like a jackass. When Percy's handler, Gruff Cop gets upset, Kevin bites him and they discover his new fang contains paralyzing neurotoxins.
