Dwayne "The Rock" Johnson has built a reputation as one of the nicest guys in Hollywood, but as a youngster, he was known more as a troublemaker with a quick temper.

In a cover interview with Alan Shipnuck for Sports Illustrated, Johnson tells a crazy story about the time he tried to rip out the tongue of former University of Miami teammate Kevin Patrick during a fight.

From SI:

Johnson's frustration at not being an impact player boiled over one day after practice, when he was heckled by his friend and fellow linemate Kevin Patrick. "I was always running hot because I wasn't getting the playing time that I thought I deserved," says Johnson. "The truth of the matter is Warren Sapp was just a better player, but when you're young, you can't see that. Me and Kevin were in a coach's office, and he was talking s---, as always, but this time I just lost it. It was like a movie fight - the desk got turned over, stuff was flying all over the place. We spilled out onto the weight room floor, still going at it. He wouldn't stop talking, so I decided to pull his tongue out. I stuffed my big ol' hand into his mouth, and I had a couple of fingers around his tongue, but it was so damn slippery! I was quite serious about pulling it out, but I couldn't quite get a hold of it. Eventually I gave up, the fight ended, and two minutes later we were hugging each other. It was so dumb."

Johnson was never able to make it to the NFL, and admits he still wonders what his life would've been like if he had.

"I think about it all the time: What if I had been a little better at football? Maybe I would've had that success and become complacent," he said. "But I didn't get to walk away (from football) on my terms, and that lit a fire that still burns. I wanted that life I had envisioned, but I had to find another way."
