It Only Took Ronda Rousey 6 Seconds To Make Jimmy Fallon Submit

Earlier this month, UFC women’s bantamweight champion Ronda Rousey proclaimed she could beat "100 percent" of the male UFC fighters in her weight class.

Last night, she proved she could definitely beat Jimmy Fallon.

The "Tonight Show" host convinced Rousey -- aka "The Arm Collector" -- to demonstrate "the armbar," one of her signature moves. According to Fallon, it "almost snaps peoples' arms in half."

After laying out the ground rules, including the selection of a safe word (Fallon chose "Rumpelstiltskin," naturally), Rousey walked viewers through the maneuver.

We're not going to spoil this one for you, but it ends with Fallon screaming "Rumpelstiltskin," face down on his desk.
