A girl (played by episode host Emma Stone) sings in her school's cafeteria about breaking her arm by slipping on grape jelly. Her situation only worsens as each verse ends with her falling again, breaking a new appendage until she ends up paralyzed, confined in a wheelchair, and only able to talk through a computer program a la Stephen Hawking. The grape jelly (Andy Samberg) comes to life and claims not to be the cause of the girl's broken appendages. (thetvdb.com)
