S2·E38 The Seven Voyages Of Cynthia

While Stu and Drew are cleaning Drew's boat, Chuckie and Tommy shanghaied Cynthia so she could be captain; however, when she got lost in the sewer system, it broke Angelica's heart. She did get her back, but not without sailing miles and miles in the sewers and taking a bath in toxic waste. Meanwhile, after being chased away by Angelica, Spike hitches a ride in a garbage truck to the city dump, which doubles as a "scenic overlook."
