Sophia: Yes, it's a number.
Me: "I have to go number one" means you have to go pee pee.
Sophia: (incredulously) Nooo!
Me: Yes, and "I have to go number two" means you have to go poo poo.
Sophia: Nooo! It doesn't mean that!
Me: Yes, it does.
Sophia: What does "I have to go number five" mean?
Me: It's just a number.
Sophia: (emphatically) No, what does number five mean?
Me: Uh, it means you have five fingers on your hand.
Sophia: What does "I have to go number pee pee" mean?
Me: That doesn't mean anything.
Sophia: I know. I'm just playing.
