There was a knock at the bedroom door. Jon/Sherry opened it, seeing his little brother Mikey standing in the hallway.
"Um, which one are you?" Mikey asked, when he saw two Moms.
"I'm Jon."
The real Sherry marched over to Jon/Sherry and said "You promised to act like me. Don't go around telling people that you're really Jon."
"How are people going to tell us apart then?" Jon/Sherry asked.
Sherry hadn't thought about that.
