did we ever find out what "A.C." stands for (ie--what is A.C. Slater's name)?

"Albert Clifford"

Reallly?

Can you tell me which episode that was, and maybe a brief synopsis to jog my memory?

Hi,

It was the episode where Slater's old girlfriend (from a while back) came to Bayside and then started dating Zack. Slater was dating Jessie at the time so it was all very awkward for him 'cause (if I remember correctly) once he saw her he became kind of sweet on her again (or at least Jessie thought he was). That was the first time his name was revealed.

The second time (I believe) is when Slater's sister came to Bayside from Germany and kept calling him by his full name. Since he was kind of made fun of in this episode, his actual name was a bigger deal than the previous episode where it was revealed (it was kind of part of the story for this episode).

Thanks, man.

Those episodes vaguely seem familiar, I'm not sure why I don't remember them.

No problem. I just looked them up on epguides.com.

The first one I mentioned is listed as number 72 - "Love Machine"

The second is number 77 - "Slater's Sister"

it would've been funnier (and scarier) if you'd remembered that off the top of your head

I thought Slater's sister was a babe

Whoa, back the truck up.

I thought Albert Clifford was first revealed when AC's dad tried to make him go into the army and he finally convinced him otherwise. I could have sworn Dad referred to him as Albert Clifford when he got pissed off.
