Peanut, standing naked in front of the toilet: Hey, Mom, I know how to do "squishies."
Me: I don't know what that is.
Peanut: Oh, it's from Captain Underpants. It's where you take two packets of ketchup and put them under the toilet seat. Then when somebody sits down....
Me, lightbulb clicking on: Ah! So that explains why there was a packet of hot sauce in the toilet this morning.
Peanut, eyes wide: Wah? Huh? No there wasn't. How did that get there?
Me, giving him the eye: Peanut.
Peanut, eyes wider, shaking his head in disbelief: No-o.
Me, staring and silent.
Peanut, looking down and pulling on his penis: Heh, heh, penis.
Peanut: Moon did it.
Peanut: Ok, I do not know how that got there. I mean, I put a packet of hot sauce under the toilet seat, but I took it out and put it in the trash.
Me, shouting into the next room: Moon, how did a packet of hot sauce get under the toilet seat?
Moon, shouting back: Exactly how you think it did.
Me: So, you're saying you knew about it?
