I was in my bed, unable to sleep, at 3:00 AM, when suddenly a machiavellic idea came to my mind. There was this one kid who pissed me off day after day after day in grade 8,and i'm wishing to pay...

I think it's feasible, if I manage to just get away after the deed is done, I will probably not hear from him again as I am totally uninterested in his circle of friends.

Thanks for the input all... didn't think about the paper bag option. (ah and that includes you too screaming,of course I wonder what better simple humouristic option you could come up with.)
