How Did You Injure Yourself Exercising?

My sister had a major treadmill fail last week. She's lucky to be alive after her hair got caught in the track! She and the people in this video can't be the only ones with exercise fails.

I have fallen off a treadmill. I broke a toe by dropping a weight on it and I gave myself a black eye with an exercise band. I'm basically a hot mess at the gym.

What is your exercise fail? What is the strangest way you injured yourself working out?
