We were egged years ago but it had nothing to do with Halloween. We had the local cops alerted for possible trouble so the second I said my name, they were over in 2 seconds and got the kids. We were told to make sure all the egg stuff is off the car ASAP because it causes damage to the paint.
When I was around 12 and we lived at our old house, I caught the horrible brother of a girl from school (we hated each other) toilet papering our lawn and just about to toss an egg. I was fearless in those days, so I ran over to him and punched him in the mouth. (no lectures, it was an automatic reaction and i truly am non violent) Anyway, never another problem from their family from that day on! And I made him clean it up and he did!
