Another one of Lisa's birthday comes and goes and the whole family forgets once again. She has had enough of it! She confronts the family about it, and they are clueless. She's had enough. She goes to her room and plots revenge. Later that night, she cooks up a special soup for dinner, the special ingredient? Rat poison of course. The family sits down to eat it, and they all begin to feel ill. By the end of the dinner, they are all sick to their stomachs and lisa is laughing hysterically.
