Kelly of Arc, Junior-Prom Martyr
Finally! Everyone (sort of) ends up with the person they're supposed to be with. Kelly and Zack, Jessie and Slater, Lisa and Screech, Random Nerd Alan and some cake... Oh, and Kelly's dad gets laid off, ostensibly due to "world peace." Guess the SBTB writers forgot about that pesky little Gulf War. Not to mention the Israeli-Palestinian conflict. And...oh, never mind. Accuracy is not the reason why we love this show.

Never trust those accents
Zack starts a teen line to give the gang yet another excuse to showcase their range of really bad accents (not to be confused with the teen line Zack starts so he can pick up handicapped girls). However, things go awry when Zack displays his complete and utter incompetence at using call waiting and manages to convince Kelly's kid sister that he's in love with her.
