Every year, millions of people swarm malls and big box retailers on the Friday after Thanksgiving in hopes of copping a half off HP laptop or discounted bicycle. However, mixing impossibly low prices with limited inventory can be a recipe for disaster. "Black Friday" is more than the year's biggest shopping day, it's a competition. And, if you don't come ready to play, you might get trampled to death by soccer moms in the Target parking lot or hit over the head with a scooter during a feeding frenzy for the last X-Box.

Well today, Complex News is counting down some of the worst "Black Friday" moments in recent history. Check it out in the video above. Oh, and be careful if you're bargain hunting today. Saving 30 percent on the Harry Potter DVD box set isn't worth a broken nose.
