Since there is an unbelievable amount, I'll try to boil the pics down to a few of the essentials throughout the years (only some of these guys aren't still crushes now, but most still are).
T(w)een Year Crushes:
Mark Paul Gosselaar -
Saved by the Bell, "Zack Morris"
Michael Manasseri -
Weird Science, "Wyatt"
I doubt I was the only fan of the show grateful for the episode where they finally stopped treating him like a nerd and had another character notice he was quite ripped.

I actually took a bit of flack in the previous thread for this inclusion. Let me tell you right now: if you don't agree this guy is hot, you have no taste in men. I know his character on the show was insufferably clean and goody-goody and "gee, golly, gosh," but there's no short-changing that body.
