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. Shocked, Lisa opens the front door to save her hamster, breaking all the ramps, and leaving the house all wet. Marge berates Homer for not providing a more sensible solution to fix the roof. Angered, Homer decides to go to Moe's Tavern, but is kicked out when he sits on Lenny's birthday cake by accident, shaped in the form of Lenny's favourite bar stool. Feeling depressed, Homer finds another bar, "Knockers" (A parody of the restaurant Hooters), where he meets a friendly man named Ray Magini. The two talk, and Homer finds out that Ray is a roofer, so Homer asks him to fix his leak. Ray agrees.
