S5E10: Peter's Two Dads
My God. Nobody's ever beat me at the game of drink.
Now do you believe that you're my dad?
Nobody but a McFinnegan could handle that much of the creature.
You're the broth of me own stubby shillelagh, all right.
Welcome to me family, Peter.
Did you hear that, Brian? I'm a McFinnegan now.
I can forget all about Francis.
You know, there's something you should always remember, Peter.
