Pranks and Greens - 22 Nov 09

Fed up with Bart's constant pranks, Principal Skinner tells Bart that there is a former Springfield Elementary student hailed as the best prankster ever - even better than Bart - but he won't divulge the legendary student's name. Bart finally gets Groundskeeper Willie to reveal the prankster's identity: Andy Hamilton (guest voice Jonah Hill). Bart tracks down Andy, who is now 19 years old and hasn't grown out of his pranking days. Bart and Andy become fast friends until Bart gets Andy a job working for the ultimate clown.
