What Carrie did not know was that the items from the factory were all designed to get the other woman out of the way so Carrie could supposedly get her husband back and the Pocket Rocket was just another way to do that.
So when Carrie got to the door in the deliveryman outfit, as the pig passed she lit the fuse and shoved the explosives into the rocket. Carrie then looked up to see John's body in just a towel as the rocket fired.
The rocket shot into the room and went around once before in shot up under the towel John had on.
John let out a loud OOOOOOOOOOH as her hair shot out to a new length and her eyes looked to be bulging out.
Carrie said "OH SHIT" as she know something was wrong as she seen the look on John's face but before she could do anything John was launched into the air blasting threw the ceiling leaving followed by a trail of smoke in the form of "OOOOOOOOOOOOOOOOOH" leaving the towel to float to the floor.
Carrie ran out from under the veranda roof to is the naked form of a buxom woman shooting past the moon followed by the "OOOOOOOOOOOOOOOOOOOOOOOOOOOH."
Carrie said "OH shit now I have to find her again. This is beginning to be a lousy trip."
Carrie then notice how dark is was getting.
