"Hey, Mommy! Do you know what happens when you flush?"
"Tell me..." (thinking this could be interesting)
"Well, the poop goes in the toilet, and when you flush, it goes down the toilet. Do you know where it goes next?"
"The poop goes into the ocean. It does!"
"Uh-huh... and how do you know that?"
"Oh, I just made it up."
Wow. I am sure am glad I have him to clear that up for me!
