Warning: bad Metallica cover bands will induce you to new levels of headbanging frenzy that can only end badly, like it did for this woman.

When repeatedly told to avoid a dangerous object, it's only rational to do the opposite and face plant directly into it, as this girl demonstrates for us.

A Steelers super-fan celebrates their Super Bowl win a little too much and falls down drunk. Don't worry, there happened to be a car near by to catch his fall.

Trying to reach first on an infield single, this girl gets clocked in the head with an errant throw from across the diamond. As coach would always say, walk it off.

While training to compete on Ninja Warrior this man proves to be more ass than assassin. At least It's better he embarrasses himself over here rather than in Japan.

If the Knicks not making the playoffs and not having a first round draft pick wasn't enough, their cheerleaders didn't have a great season either. At least one cheerleader didn't anyway.

Who let this guy announce that day, anyway? If I had heard that live I would've been more worried about whether or not the guy was going to keel over than the winner of the race.

This reporter tries to show viewers how easy it is for a car robber to break into a car. Turns out he should stick to being a reporter, because he can't even impersonate a criminal for the sake of demonstration.

Although two robbers on a motorcycle have a sword to defend themselves, these Chinese townspeople come to a victim's defense with all sorts of makeshift street tactics.

Leave the guitar swinging to the pros fellas, or at least make sure that no one is within a 5 foot radius of you, just saying!

There is a fine, fine line between character and actor. Unfortunately for this actress, she gets a little too into her part and ends up slamming into the floor.

Maybe it was the Soulja Boy song in the background that distracted this athlete. Whatever it was, he sure won't be headed to the Olympics any time soon.

Normally, track and field would not be considered a contact sport. This is an exception.

These Russian guys look super plastered. Maybe, they're bodies have been taken by evil spirits. Or, they could just be abstract performance artists...either way, it makes for good entertainment.

Jumping over the hoods of cars is never safe for you or the car, as this guy learns first hand. He'll never land that coveted role in the next Dukes of Hazard remake.

Gentlemen, clearly parkour was meant for outdoor environments, you should know better. Also, always make sure the object you want to hurdle over is stable. Knowing is half the battle.

While you may initially think of this performance as a mess, the only failure the "singer" commits is forgetting to hold on tight. His commitment to showmanship, on the other hand, is A+.

Maybe this kid should stick to something with two wheels because he definitely doesn't have a knack for the unicycle.

It's understandable if some damage is incurred while docking (we're all human), but his must be the worst parallel parking job I've ever seen. How did this boat captain ever get a license?

This kid, who fancies himself some sort of Clark Kent, attempts to leap from banister to banister on his front porch. Clearly, he can't be bound by physics or terrible ideas.
