Using the gun on Jon.

As Mikey got off the bus (which had stopped on his street, since school was already over), he saw Jon in the driveway, working on his dad's old car. "Hey kiddo," Jon said as Mikey approached him. "That's a cool looking toy gun you've got there." "Thanks," Mikey said as he took aim at Jon. ZAP! In Jon's place was standing a little girl wearing a frilly pink dress and holding a doll. "That's a very cute dress you're wearing, Jonny." "Thanks, it's my favorite." ZAP! Jon was now a vegas showgirl. ZAP! A bearded lady. ZAP! A japanese shcoolgirl. ZAP! "Ah, perfect," Mikey said as he gazed at the new form Jon had taken.
