What’s the strangest thing you have ever seen in your life?

Well there was this one time that I was walking past a park at night with some of my friends. We started hearing these weird metallic noises, and we shine a light over into the park to see what’s going on. There are these two dudes swordfighting; and I don’t mean fencing, these guys had fucking broadswords. Whether or not it was casual is kinda debatable considering that they looked like they were actually trying to kill each other.
