Dumb and Dumber Driver T Shirt Relive a hilarious scene with this fun Dumb and Dumber t shirt! The Dumb and Dumber Driver T Shirt is gray. It features a black-and-white image of Jim Carrey as deranged imbecile Lloyd Christmas from the movie Dumb and Dumber. He says, "It's OK! I'm a limo driver" when he rushes onto a jetway only to plummet onto the runway!
