Punishing bad programmers

So I have this faggot at work, who is a total ass. He writes shit code and makes comments on the level of ``i++; //adds one to i'', and I can't even tell if he's being sarcastic or not. Should I like, set him on fire, or something?

Plant CP in a flowerpot and give it to him with a card that says ^_``Get Better At Programming Soon!^_''.
