Tony: Well at least you won't get Anthrax, that's Ace!

Jenny: Actually you need to have four of them, and one every year.

Tony: Oh, that's a bit gay!

Jenny: And after all of that there is still a risk of getting Anthrax

Tony: That's Gayce!

Otherwise known as "BOHEMOTH IN SPANDEX".
This ravenious beast plays table tennis and if she glares you with her artificial blue eyeballs, beware, shes hungry.
This fat creature will attack when you hit the wrong angle in table tennis, or if you do not look at the table whilst playing.

Beware because this monster will not tolerate smart-ass - ness from players and she WILL tell you if you need a haircut. But no one dares telling her how horrid those tight spandex tights are...in fear of having their bones grinded to make her bread.

Gayce- the nickname of a horrible person whose real name is Grace. She may be smart, but unfortunately, her intelligence is the only thing that she will ever have. She tries to flirt with many guys, but her over self confidence and rude personality never gets them hooked onto her. Whenever she has a new crush, she always hints it to EVERYONE about it, thinking that maybe they actually give a damn. But the reality is, they don't. She likes to pretend that everyone is her friend, and if there's someone who doesn't like her, Gayce will stalk them and try to force them into a friendship with her. If that person is mean to her, then Gayce will go and spread false information about that person to other people and snitch on them for things that they didn't even do. And after all that is over, she will still continue to try to befriend you, even if you are sending off the strongest hints of disapproval. If you ever see a Gayce, STAY AWAY FROM THEM.
Friend: "Oh shit, Gayce is walking right towards us."
Abbie: "We have to walk away I really don't feel like dealing with her right now".

Anyone that ruins the moment with a remark that they deem witty and clever but is actually extremely lame and gay. Similar to any Slater comment on saved by the bell
Zack Morris was teaching the audience a valuable lesson that he learned in this episode when GayC Slater interrupted and made him forget.
