Questions and Answers:
Alright, so I my friend just egged someone house, and I want to know what the chances of him getting cought are?
Well, if this post is any indication of your/your friend's intelligence, I'd say the chances are pretty damn good.
I could speculate that, based on how stupid you seem to be, that you would do something foolish, like shout your name to the egging victim before throwing. Or perhaps, you waved to a security camera while holding a carton of eggs in the vicinity. Maybe the house was across the street from a police station.
I think it's safe to say you are screwed. If there is a God, and he is a benevolent God, you will be arrested, put into a juvenile detention center, and there you will receive some sort of education, which is apparently lacking in you school system.
