The friendship contract that Jimmy and Cindy signed (and was later ripped up) did not contain the exact words that they said as they signed it. After Jimmy signed it, it read:
"I, Jimmy Neutron seriously bury the blood stained hatchet with Cindy Vortex that has ever so complicated the lives of the residents of our town, Retroville, and the rest of the galaxy. I promise to get along and try to understand the genius of Cindy Vortex and kiss her hiney.
I, Jimmy Neutron also agree to do my best to see things her way, and not to create crazy inventions to prove her wrong that otherwise may turn the town upside down and create the disturbances they have in the past."
