Mia St. John
Month/NSFW Link: November 1999
Athletic Claim To Fame: As the only pure boxer on our list, Mia made her pro boxing debut on Valentine's Day in '97 and knocked out her opponent in the first round in 54 seconds. How's that for drop dead gorgeous? In her 11-page pictorial in Playboy, she made sure that everything maintained a boxing theme, so that everybody knew she was a fighter first and foremost.
