I got an egg thrown at me last halloween. I caught up with them 2 blocks later (punk kids in a Corolla) and kicked the passenger side mirror clean off. Ruined one of my favorite shirts. I had to ride over a curb at 15mph through a crowd of people to get away from the car. They continued to throw eggs (I was too far away and moving to fast for them to hit me) and I turned into an alley and they kept going. I'll bet their mom was mad about her car missing a mirror
