The Simpsons Guy (S13E01)

Two of the most iconic and revered families on television come together when the Griffins meet the Simpsons. Peter and the Griffins end up in Springfield, where they are greeted by a friendly stranger named Homer Simpson who welcomes his new 'albino' friends with open arms. The families get along famously: Stewie and Bart make out like bandits when Stewie trades in his mind-control device for a good old-fashioned slingshot, Lisa takes Meg under her wing and teaches her the saxophone, Marge and Lois ditch housework for a little bonding, and Peter and Homer fight over the best beer in town - Pawtucket or Duff.
