Potty Humor

Me: Run in and go potty for quiet time! You get to go potty on the blue water!

Ava: Huh?

Me: I cleaned the potty with blue cleaner. Yellow and blue make green, so when you pee on the blue water it will make it green.

Ava: Okay!

A few minutes later....

Ava: What do yellow and blue and brown make?
