When Street Luge is just not hardcore enough

So, the other day I was curious-- what are the most extreme sports out there?-- My list, prior to being informed, would have been something like this:

1. Ultramarathoning

2. Kite-boarding

3. Elk hunting

4. Rugby (I mean, you've seen those dudes after a game, that's frickin' hardcore)

5. BJJ

6. White Water Kayaking

7. Mountain Boarding

8. Trick Bikes (like on the X-games, those bikes that do tricks similar to skateboards/roller skates)

9. Free climbing

10. Free running (parkour, I think, is the formal name)

11. Luge (in all forms... street, snow, ice, fire, whatever)....

12. "Ghost Ride the Whip" (may not actually be a sport but... come on, you've gotta love some ghost riding... for those of you who don't know what ghost riding is, please youtube it... hours of entertainment await)

13. Being an astronaut (not sure if that's a "sport" but I'd do it for recreation!)

14. Bowfishing (Hardcore points are owed to bowfishers-- They are shooting a FISH with a BOW AND ARROW!!-- the physics of doing that alone boggle me, not to mention the fact that you have to be able to shoot a bow and arrow extremely accurately)

15. Speed skating

Anyway, those seemed pretty awesome to me... until I looked on my good friend, the World Wide Web, and found out that I have a really sissy perspective on the term "hardcore."

Well, I found this:

Okay, so not all of it is that special, but check out sport number 2: Limbo Skating... I mean... that's ridiculous. Everything in my life that I thought was hardcore has just become equivalent to eating a pile of marshmallows.

I'm going to go make mass carriers now so that I feel like a bad @$$ again.
