An Oregon man was showing off his gun to a friend when dropped the weapon. It went off and shot his friend!
Also, Oktoberfest is in full- swing in Germany and, as you'd imagine, people are getting very, very drunk, and very drunk people often puke. Earlier this week, someone got very, very drunk and started projectile vomiting. A stream of vomit hit a tiny bird that happened to be flying by and knocked it to the ground. Then the puke dried on its wings and the bird couldn't fly. Honest mistake. The bird was eventually rescued and washed clean of the revelers "gently used" stomach contents.
Have you ever made an epic mistake that left you saying, "My Bad"?
