i live in israel, and there's a holiday here called 'shavuot', and it has some traditions like... you guessed it! throwing eggs (i want to mention it's something that the youth invented and not the religion itself) so me and my friend decide to go out and throw some eggs, streets are half empty because people are afraid to get an egg thrown at them, pretty hilarious in my opinion.
so we find some kids our age and throw eggs at them, no hard feelings, all laughs and all, they weren't mad.
after throwing a few eggs we see a kid standing with his back to us and we decide that this is going to be the best sneak attack ever! 
so we egg this kid, he rotates and he's crying because of us, hearing shouts from behind us we see his dad running at us, panicking we both take off and start running as fast as we can, eventually his father caught up on us and called the cops on us, telling us his son was mentally challenged... oops? in the end it ended up good, we said we're sorry and didn't mean to, it was all for laughs and giggles.
