Patrick: Yum, yum, yummy pancakes! I could just eat you up! (grabs a knife and fork) Oh wait. I will! (gobbles up a pancake)
SpongeBob: Pat, can I have one- (Patrick punches SpongeBob)
Patrick: NO!!! My pancakes are my pancakes. And my pancakes deserve to be eaten by their owner. Me.
SpongeBob gets up.
SpongeBob: All the better to share them with!
