Dennis: (About Saved by the Bell: The New Class) The last year and a half of The New Class weren't a whole lot of fun for me - I'll be honest. They were takin' liberties with Screech and Mr. Belding that just weren't funny and I thought that they were kinda disrespecting the audience a little bit towards the end.
