Meanwhile, Bart gets bitten by a Chinese mosquito that was in his Krusty-saurus toy, and becomes infected with "Panda virus". To prevent others from getting sick, Dr. Hibbert puts Bart in a plastic bubble for the next few days. Bart initially has trouble adapting to life in the bubble; he has trouble eating and Homer gives him a bath by filling up the bubble with the hose and rolling Bart around the house. Lisa tries to keep up her double life, attending poetry readings at night wearing a beret and falling asleep in her second grade class during the day. While going to Springfield University, she is tracked by Milhouse, Martin, and Database who see her ride away. At a lecture about "Itchy & Scratchy" cartoons, Milhouse blows Lisa's cover and she flees at being unaccepted by her friends.
