Jon looked down at himself and saw that he was wearing little boy's clothes, even though he was still a teenager! It must have been a personality swap that happened.
"Oh god, what happened to me?!" he heard his brother yell. Jon looked up and saw him standing just a few feet from him. Gone was his pre-teen T-shirt and pants. He now wore a smaller version of the type of clothes that Jon usually wore.
"Mi ... Mi ... Mikey," Jon stuttered (Mikey always stuttered when he was nervous). "It's okay."
"How is this possible?" Mikey asked, settling down, but still freaked out.
Jon didn't bother giving him an explanation. Instead, he reached out and grabbed his hand and said "Swap."
