The weirdest that ever happened to me was having those tiny bombs that can incinerate a bin, and that kids play with sometimes and then losed their hand, thrown at us (us being a group of about 15 people who were counting down for new year, just like everyone else on the grassy field, since at twelve the fireworks started) by a few 7 to 10 year olds. A friend of mine got hit on the head by one of the smaller ones, she was mildly burnt.
Now that might not be too weird, the weird or perhaps creepy thing was that, being tough and such as we are, we decided to have a talk with those kids parents, who were standing right behind their offspring.
They didn't like the idea, and started threatening us, with the police of all things, because we were harassing their children!! And that's when one of the fathers decided it would be a good idea to start throwing some of the many empty glass beer bottles they had accumulated at us.
At least it wasn't something personal or anything xD
So, in a nutshel, some people are crazy and should be sterilised.
