Somewhat of a goof: In The Max when Tony invites Kelly, Jessie, and Lisa to join him, notice when Jessie misses the chair the napkin dispenser on the table falls over. It causes a salt shaker to fly off the table and hit the floor. The shaker is clearly heard smashing on the floor when the shot cuts to Jessie swiping the chair from the extra, and when we see the girls and Tony again Kelly has a "WHOOPS" look on her face like she's trying not to laugh.
Slater: Okay, Preppie. While you're here rehearsing, Kelly and I are going to the beach.
Zack: Kelly, this news disappoints me verily. I thought you and I could go over some more lines from Romeo & Juliet.
Kelly: Oh that's a good idea, Zack. Sorry, Slater.
Slater: What? I don't believe this. You'd rather study than go to the beach?
Zack: Partying is such sweet sorrow... chump.
Mr. Crane: Everyone tell me your names...
Screech: I'm Screech.
Slater: I'm Slater.
Kelly: (dreamily) I'm yours.
Zack: I'm bummed!
Mr. Crane: (as Romeo) With love's light wings did I o'erperch these walls. For stony limits cannot hold love out. And what love can do, that dares love attempt.
Kelly: (as Juliet) If my kinsmen see thee, they will murder thee.
Slater: Go kinsmen!
Zack: Oh to be that straw sitting in my lady's cup! Gladly would I be made of plastic and risk drowning in a sea of cola to touch fair Kelly's lips.
