Hal: Hey, remember before he was born and I had that Harley Da-?
Lois: No motorcycles ever! You do not talk about motorcycles. You do not think, you do not wish, you do not even reminisce about those stupid, idiotic death traps. They do not exist. Motorcycles do not exist! Say it!
Hal: Motorcycles do not exist.
Lois: What does not exist?
Hal: I don't know.
Lois: Good!
