John took the device in his hand. "I'm going to try something else" he said.
Outside it was dark. There weren't many people about, so John and Frank walked down the street. Round the corner from Frank's house was a small area which contained a number of shops, a pub, and a club. A girl was coming out of the club, drunk, with her boyfriend - or at least, someone who she had picked up inside. The man was obviously hoping for something more, as he kept putting his hand on the ladies rear.
"What are you going to do, then?" said Frank.
John held the device and pointed it at the woman and pressed the red button.
"So," said Frank, also holding the device, "Who are you going to swap her with, then?"
John turned to Frank and looked him in the face. "You" he said, and pressed the button again.
Suddenly, he saw Frank's head replaced by the one of the woman, a cute face with shoulder length blonde hair. As Frank was touching the device, he of course knew what was happening. Or rather, Frank's hand was touching the device. So when the girl/Frank looked at John s/he realised what had happened.
"What the f..." she started to say in her voice. "What have you done to me?" she looked down at her new manly body. "What's happened?" she shouted, attracting attention from some of the people hanging outside the nightclub, though of course they couldn't see anything wrong.
One person who didn't notice, or chose to ignore, was Frank/woman. His head atop a body wearing a figure hugging black minidress, black tights and high heels, s/he was too concerned with kissing the guy s/he had picked up his/her hand on his crotch, whilst the guy was rubbing Frank/woman's breasts.
