Since we know they starred three times in Saved By The Bell, Saved By The Bell: The College years, and the Las Vegas T.V movie, which do you believe is more a top or bottom. Regarding their Saved By The Bell characters. Mark Paul Gosselaar seems more of a bottom because despite his Zack Morris preppie character that would do trouble and whatnot, he seem eager to be a bottom to Mario Lopez's AC Slater. He also seems like the type to take anything up the ass. It wouldn't suprise to know is more a bottom than a top. Everyone's favorite AC Slater or better yet known as Mario Lopez. Somehow, I could imagine him topping like a champion. Just imagine those muscles(he still looks nice) of his as he fucking Mark...he is almost predetorial a bit. But that's my opinion, but who do you think would bottom or top one another if there was a sex tape. Your choice.
