I have two questions: (1) What glue do you guys suggest so as not to have the paint eaten off the roof of my car? Or some other form of attachment to keep the mug on the car? (2) Do you guys think this is funny? Because I want my most honorable Car Talk Guys’ stamp of approval of humor before I go ahead with my prank on the world. Thank you very much.
