Jeff met up with Eddie at school and placed his phone on a table. That table also had Chandlers phone and they started talking, they then learned about sex and decided to try it out. Jeff's phone layed flat on the table ready for Chandlers phone, Chandlers phone prepares Jeff's phones headphone jack for its gigga charger. Chandlers phone sticks it in and takes it back out like in the videos, they find out they love it and keep doing it.
The end? lol
