Jeff was about to make a some new changes to his little sister, Emily, when he heard a knock on the door. He walked back to the front of the house, dropping the emitter on the table as he went to answer. The new guy was his buddy, Shane, who had been his friend since kindergarten. Shane was more athletic, and was one a bunch of teams. Jeff unlocked the door, feeling slightly warm, and pulled it open. He looked outside, but Shane was no where to be seen. "Hey, Jeff, what happened." Jeff looked down. Shane, a kid about 6'0" even, was now three feet lower then Jeff.
"I... I don't know." Jeff said as he turned to look into the house. He spied his elongated sister holding the emitter. She was a good two feet shorter then Jeff, leading him to conclude that Jeff was well past 9'0", possibly close to 10'0". "Scratch that," the giant said as he turn back to Shane, "it's a new computer program that allows me to make changes to someone's body."
"Dude," Shane yelled as he entered the house, "can you do something to me? I would kill to be taller for basketball season."
Jeff took the pair to the computer room and sat down in the chair. He looked awkward. The desk was not built for someone of his height by the furthest stretch of the imagination. The program booted up and the emitter scanned the room, bringing up the bios of all three occupants. Jeff turned in his chair. "OK, Shane, what will it be?"
