dude the way to do this is say something that would really piss him off, wait till he pushes you and then bust him right in the temple. he wont get up for a couple of minutes. i know how you feel except not really. i was mugged by three kids in October and that really pissed me off. i bought brass knuckles so the next time i see those fuckers, i will give them a hit they wont forget.

oh by the way, i hope your mom gets better. i lost a loved one to emphizima as well (my grandmother). and mastachronic knows what he is talking about, if you decide to hit him, dont stop hitting him in the face till ur sure he wont get up
