The episode starts off with the Masqurade Ball upcoming and with Tori witnessing both Zack and Slater kicking game to various chicks in their quest to find dates. She calls them both out on it and calls them pigs. In turn Zack and Slater interpret it as her playing hard to get. So they make a $50 bet to see which one will be able to kiss her on the lips for at least 3.5 seconds while having a witness present which would ensure the winning of the bet for whoever accomplished it first. This is when the hilarity starts to ensue. Slaters first attempt to kiss Tori fails when Screech does his trademark annoying thing to mess it up. Next Zack takes Tori on a movie and romantic dinner date and things are looking good for Zack to win the bet. Just as Tori prepares to kiss him thus making Zack the winner, he has a revelation that he likes her and doesnt feel comfortable using her like this. Screech once again opens his big mouth to Tori and explains everything about the bet. Once Tori finds out what costumes the others will be wearing she sets it up to sabatoge each and every one of them. Both Tori and Lisa arrived to the ball in cat costumes. Unfortunately Zack mistakedly thinks Lisa is Tori amd he expresses his feelings for Tori to her. To Zacks shock and amazement, Tori pulls the cat mask off and reveals that its really her and while Zack felt a little embarassed you could tell that he felt a huge sense of relief that it was now in the open. Tori agrees and the two share a nice kiss at the end.
The other plot of the story is the Screech/Lisa love letter crap thas had previously been used in an episode of Good Morning Miss Bliss. Basically Lisa mistakedly thinks Zack and not Screech is her secret admirer. It leads to a bunch of false assumtions and accusations including a hilarious scene in which Ms. Culepper thinks that Mr. Belding is hitting on her and vice versa. The most memorable scene of this episode was watching Screech (Gumby) and Slater (astrounaut) have a make out (in costume) session and both their reactions after they unmask themselves was priceless.
Overall i enjoyed this episode but it couldve been better IMO. Too may different storylines were spreadout throughout the episode and at times it was hard to catch up on who was going as who to the costume ball. In the end though it was still classic Saved By The Bell with its tremendous amount of comedy and likeable characters that make this show my favorite series of all time.
