Long before she formally started her professional MMA career, Ronda Rousey says she engaged in some unsanctioned bouts on the streets of Los Angeles ... against men. Rousey retold the story to Sports Illustrated recently of how she as a young judo prodigy would challenge boys to scraps to earn money for frozen coffee treats.

"Me and my friend Jackie, after school, we would walk over to the Promenade, and Jackie was like my Paul Heyman. She would be like, 'I bet my girl right here could beat you up for $10.' And then some guy would be like, 'Ehh, whatever. I'll take that bet,'" she remembered.

"I would throw him to the ground, either give him a choke or an arm bar. We would get him to say he gave up, then take his money and go buy frappuccinos (laughs)."

Rousey may now be the highest paid MMA fighter in the world, but she's always been down for a scrap, even for smaller stakes.

"Those were my first pro fights," she joked. "Will fight for frappuccinos."
