After traveling to Aspen, Colorado, to return a briefcase to a woman he had chauffeured to the airport and subsequently fallen in love with, Lloyd Christmas is perturbed when his friend, Harry Dunne, arranges a date with her shortly after they arrive. In an act of revenge, Lloyd fills Harry's tea with laxatives. Upon Harry's arrival at the woman's house, he finds that he needs to use the bathroom. After having explosively emptied his bowels in to the toilet bowl, she tells him it doesn't flush. Hilarity ensues as he desperately tries to fix the toilet whilst hopelessly tries to waft the horrific stench out of the window.
