#1. "Mr. Plow": Season 4 Homer starts his own snow-removal business, competing with his buddy Barney -- whose life he saves on a treacherous road. The two end their rivalry, suggesting that even God can't pull them apart. At which point God, miffed, melts the snow and puts them out of business. Once heard, the Mr. Plow song will stay in your head forever.
