Spiderman Town

This morning, while making breakfast, I heard Jacob come into the kitchen.

"Mommy, can I go to Spiderman Town?"
"Sure!" I turned around to find Jacob striped down to his underwear. "Jacob! Why are you only in your underwear!?!"
"That's one of the rules at Spiderman Town. You can only enter if you're wearing just underwear."

Jacob skipped off.
"Sophia, would you like to go to Spiderman Town with me?"
Sophia took one look at Jacob, "Uh, No!"
"That's OK. You wouldn't get in anyway."
"Why?"
"Because you have to wear underwear and you still wear diapers."
"Why?"
"Because you still pee & poop in your pants. And Spiderman doesn't like that."
"Why?"
Thoroughly annoyed..."Ughhh, nevermind!"
"OK"
