Well, in my opinion, this episode was certainly not one of their best of the series or even the first season. However, there were a few good lines in it which had me laughing out loud.
The plotline with Eric and the car wasn't especially funny and I think it could have been rewritten to make it better. The only part that was really funny was when Feeny forgot to take off those earrings Morgan had him put on.
Now, Cory and Shawn acting together is great because they play off each other so well, especially when they were watching the R rated movie.
