My sister's house used to get egged frequently - kids had the wrong address - they wanted to get a teacher living a couple doors away. When I used to walk quite a bit, I got egged (sorta) twice. First time they just splattered my shoes, second time - a clear miss. I figure now eggs are so cheap - the kids will stock up, it's much cheaper than tp-ing someone's trees, bushes etc. I also got sprayed with some kind of clear fluid - must have been just water - didn't cause any damage. But after that, if someone drove up near me with a window open on the passenger side - I would give them wide berth.
