The first day went a little like this:
me- Okay boys, this is what's going to happen..
ian- What's going to happen?
me- I was just getting to that. It's not nice to interrupt when someone is talking to..
ian- Sorry
me- ...when someone is talking to you. Alright, so. Today we are going to wear underpants because we are big boys, and..
kyle- You not a boy, you are Stacy.
me- Very true. I'm not a boy. Thank you for pointing that out.
kyle- Welcome.
me- Okay, because you are big boys now, and not babies like Korah, we're going to pee in the toilet.
me- *hands each of them a pair of Thomas the Tank Engine underpants*
ian- Thomas the train is a boy
kyle- NO HE IS NOT! HE IS THOMAS THE TRAIN!
*insert freakin fight here*
*fighting continues until I wrestle one down and put the underpants on him*
kyle- Hey! What's this hole?
me- That's so you can stick your peepee out of your underpants and potty in the toilet without having to pull them down.
*insert astonishing looks of disbelief here*
me- Okay, ian put yours on while I go potty, kay?
me- *heads to the bathroom, pees, comes back to the living room, notices a LOT of giggling going on*
me- What's up, goofballs?
*boys turn around*
me- *dies laughing because they've both got their peckers hanging out the front holes of their underpants*
I realize that's a long narrative to get at the funny part, but yeah.
