 At Maxine s rooftop party, Urkel shows everyone how to "Do the Urkel." But it may be his last hurrah; Willie Fuffner, his pride still stung from losing to the nerd during a boxing match several weeks earlier, offers Urkel a peace offering - a glass of punch. Only he doesn t tell him it s spiked with whiskey. A drunken Urkel staggers around the rooftop, which is good for a few yuks ... until he tumbles off the side of the roof and finds himself clinging to a clothesline for dear life. Rachel manages to save the day, and Willie and his buddy, the dim-witted Waldo Faldo, find themselves in jail.
