This Looney Tunes t-shirt features a distressed image of Marvin The Martin and his catchphrase "Kaboom!!!" When Bugs Bunny began to outwit Yosemite Sam, Looney Tunes creator Chuck Jones thought up a new nemesis for Bugs Bunny, Marvin The Martian. Marvin was quiet, calm and polite, except when he was threatening to destroy Earth with the destructive words "Kaboom".
