 During the night, Sideshow Bob reaches the houseboat and cuts it loose from the dock. Bob then ties up Homer, Marge, Lisa, and Maggie, to ensure they will not interfere with his plan. Bob enters Bart's room, ready to kill him. Bart escapes out the window and tries to escape, but he cannot jump off the boat. As a "last request", he has an idea: he compliments Sideshow Bob on his beautiful voice and asks him to sing the entire score of the H.M.S. Pinafore, to stall for time as the houseboat floats to Springfield. After the performance, Bob advances on Bart again, but the boat runs aground, and Sideshow Bob is arrested, and the Simpsons return home.
