"Don't Fear the Roofer" is the sixteenth episode of the sixteenth season of the American animated television series The Simpsons. It first aired on the Fox network in the United States on May 1, 2005, and guest-stars comedian Ray Romano and physicist Stephen Hawking. The episode is a parody of the 2001 film A Beautiful Mind. Plot A major thunderstorm hits Springfield, and Marge demands that Homer fix their leaking roof. Homer attempts to solve the problem by using Hot Wheels ramps to transport all the draining water from the roof to the front yard through the hallway, the stairway and the mail slot on the front door. Though this plan seems to work well, Lisa's hamster slides down the ramps to the front yard by accident.

Ray, however, does not arrive until everyone else has left. The two of them get up on the roof and use nail guns to nail the boards onto the roof, but they start shooting nails at each other, some hitting Ned Flanders' ride-on lawn mower next door. Ray leaves later and, as Homer runs on the roof to see him off, he crashes through the small part of the roof that they fixed, making the hole bigger. Meanwhile, Marge and the kids leave Santa's Little Helper with Grampa and the Springfield Retirement Home residents, because they seem to like him. When Marge sees the hole, she tells Homer to fix it himself, because she sees no reason to believe that his friend will. The next day, Bart and
