I can't believe no one's mentioned him yet... Arn Anderson. The man had no gimmick at all, he just walked out there calmly and whipped his opponent's ass from turnbuckle to turnbuckle. Arn and Ole Anderson are still one of my favorite teams of all time (remember how they whooped the previously indestructible Road Warriors?). I still mark out whenever I see him on tv, even though he only says on or two words before they focus on someone else... dammit. The guy didn't need a catchphrase, gimmick or props to get over like many other "greats" of the business. Arn was Arn, and dammit that was enough!
A friend in need is a friend indeed, but a friend with weed is MUCH better!
And is Jamie Noble the first man to ever turn face purely by participating in group sex? HA! Apparently so...unfortunately, this leaves Nunzio and Shannon Moore as the ?only? cruiserweight heels currently.
