Ronda Rousey is the leading lady of women's MMA, and she demonstrated her prowess on "The Tonight Show Starring Jimmy Fallon."

"Rowdy" Ronda Rousey has revolutionized the MMA world for both women and men alike. Dennis certainly has a lot of feelings about her as well, and he hashed out his stance on the famous fighter in a previous episode of "Just One More Thing."

Thanks to Rousey, getting beat up has never looked so good. And Jimmy Fallon certainly agrees--until he actually gets put into an armbar, that is. Watch Fallon squirm in fear as he dares to let Ronda put her hands on him.

How long do you think you could last in a ring with her? Is there another competitor who has a shot of beating her? Let us know what you think in the comments below!
