You may recognize Chuck Norris as the Hollywood tough guy who played a Texas Ranger on TV and a Delta Force soldier on the big screen, but he's so much more.

Chuck has shared the screen with Bruce Lee, won dozens of titles and awards for his karate skills and has written best-selling fiction and non-fiction books.

Throughout his long career he's done it all with the same humble, cowboy attitude that's made him famous around the world. But if you think you know everything about Chuck - his real name is Carlos, by the way - you should read this list of 100% true Chuck Norris facts.

1. He really knows what he's doing

Chuck's martial arts skills aren't special effects, he learned them for real while serving in the Air Force in South Korea. As a pro fighter he won the middleweight karate championship six years in a row, ending his career with 183 wins, 10 losses and 2 draws.

2. He came up with a few moves of his own

Chuck has studied lots of different martial arts over the years and combined them into his own school, called Chun Kuk Do ("the Universal Way").

3. He had some famous students

Over the years lots of big names trained in Chuck's schools. He taught martial arts to Priscilla Presley, Donnie and Marie Osmond, Bob Barker and Steve McQueen, who encouraged him to try acting.

4. Jeans by Chuck

The action star briefly dipped his cowboy boots into the fashion business, selling "Action Jeans" that would stretch for maximum comfort and let you kick above your head.

5. He's a true master

Taekwando is an ancient tradition stretching back thousands of years, so it means something that Chuck was the first person from the West to earn his 8th degree black belt in the art. He also has blackbelts in karate, judo, Brazilian jiu-jitsu and tang soo do.

6. Yes, he knows about Chuck Norris Facts

One of the oldest jokes on the web is making up "facts" about Chuck that prove he's a true tough guy. Over the years the actor has heard a lot of these, but he has a favorite:

"They wanted to carve Chuck Norris's face into Mount Rushmore, but the granite isn't hard enough for his beard!"

7. He's starred in some wacky foreign ads

TV watchers may remember Chuck's ads for the video game World of Warcraft a few years ago, but he's also filmed some commercials overseas, like these kooky T-Mobile spots from the Czech Republic.
