Me: "You and your brother are absolutely nuts sometimes. I'm going to start calling you thing one and thing two."
Son: "So, does that make you the cat in the hat?"
Me: "I suppose it does, I'm the fat in the cat. Wait, I meant cat in the hat!"
Both Son: "Mwahahahahahaha! FAT IN THE HAT!"
Two months later... still getting called the fat in the hat....
