"Your gonna be a test subject."
"What?"
"Are you hungry?"
"Yeah, I haven't ate yet, why?"
"Let's eat, my treat!"
"Alright, just wait at the food court, I'll be back."
Betty waits at the food court, while Jen goes in the store nearby, and buys a pack of adult diapers. Then comes back.
"Ok, let's eat!"
They buy food, and eat, but Betty was clearly starving, because she was eatin more and faster than Jen. After 15 minutes, Jen and Betty was stuff. Betty was about to get up.
"Where are you going?"
"To the bathroom, why?"
"I don't think so."
Jen pulls out a diaper.
"What is that?"
"An adult diaper, and your gonna use it."
