Fairies don't fart
Beth: [age 3] "My hands are magic. I can do magic things with them."
Luke: [age 7] "Oh yeah? Is your butt magic too? Do you have magic pixie dust farts?"
Beth: "No, Luke. Fairies don't fart."
Luke: "Do you pee rainbows? Do you poop rose petals?"
Beth: "No! None of that! Fairies don't do any of that! And if you don't stop it, I'm going to kick you with my magic foot!"
Down my underwear
[Scene: Luke, age 6, appears to be holding something behind his back]
Luke: "Which hand is it in?"
Me: "Hmm... left hand?"
Luke: "No."
Me: "Well, it must be the right hand."
Luke: "No."
Me: "It's in both hands?"
Luke: "No. Do you give up?"
Me: "I give up."
Luke: "I stuffed it down my underwear. It's touching my butt!"
