Tony rolled up on his bicycle and stared at the half-man, half machine thing that Jeff had become.
"Whoa, Greg, what's up with Jeff?" Tony asked.
"Oh, I changed him into my Jeep with the Chronivac, but when I tried changing him back after souping him up he didn't change back correctly."
"Hm, where's the Chronivac, I think I have an idea."
"I'm not sure that's a good idea," interjected Jeff's dad.
"What have you got to lose?" Tony said.
"Uh, I'd rather you told me before-" Jeff said, as Tony reached over and turned off the radio.
"That's better, now hand me the Chronivac, and let Tony make it all better."
Greg was excited to see what Tony had in mind, and he took the Chronivac from Jeff's reluctant dad, while Jeff flayed his head back and forth trying to turn on the radio.
Tony squatted down and started typing. Jeff could feel something happening, he swallowed hard. Then the silvery human-machine hybrid seemed to melt into a puddle of mercury, and reshaped like the second Terminator. A buff muscled version of Jeff stood there naked for a moment. Then Tony typed some more, and Jeff's silver cock and balls were absorbed into his body leaving a silver giant Ken doll in his place.
"Jeff?" asked his father.
"Yes, master. What is your command?"
Jeff's father and Greg's jaws dropped.
Before either could speak, Tony blurted out, "Transform into a riding lawn mover, Jeffbot!"
Jeff answered, "Yes, master."
Less like a Terminator and more like a Transformer, Jeff leaned forward and reshaped into shiny silver riding lawn mower.
Tony climbed on, "Hey, got to earn my $20 by mowing your lawn." Tony revved the engine and drove Jeff-mower out of the garage.
