After Carly recruits Spencer to help her prank Sam and Freddie, Spencer can not stop pulling pranks. The worst part is he didn't learn his lesson from a traumatic pranking experience (dumping garlic powder on the kids faces) when he was in high school that happened 14 years ago. In the end, Carly and the gang get the kids from Spencer's high school to come to their house. Carly goes upstairs to get her video camera, but by the time she gets down, the now-adult kids have already started beating up Spencer, and the episode ends.
