I gotta say, I didn't have very high hopes for this episode because the plot seemed sort of unoriginal. It actually turned out great! There were countless hilarious moments, especially in the first half, such as Carly's prank on Sam and Freddie and the flashback of the prank Spencer pulled when he was in 9th grade. I also laughed at Gibby's part in the second half when they were trying to prank Spencer, and I liked the fact that Drake and Josh made cameo appearances in this episode even though it was just audio. The one thing I didn't understand, though, was the ending. How did Carly get Spencer's old classmates to come over? That was never explained. Oh, well. I guess it wasn't too important to know that. The very end with the classmates beating Spencer up also didn't make much sense to me. Still, this was a surprisingly good episode in my opinion. Final grade: A-. Marebear2009, out!
