Throwing pistacios on the windshield!

don't you hate it when someone you know always wins or get the last good jellybean? you know, the guy who knows everything, everyone admires, respects, and is athletic and he always beats you at your own games (he even licks your food). you try your best to irritate him and get the last laugh, but some how he sneaks one in on you. you throw pistacios on his car and cut him off when you're driving.... yet he throws a hand full of half eaten nuts into your car and takes off .... THEN, he eats half of a piece of YOUR apple and leaves the other half on your plate when you get up to throw something away... he leaves it near the other "GOOD" apple pieces just because you know it will drive you crazy. i'm begging to think that people like this are there like gnats.... they irritate you, they fly in your face and food yet sometimes you just can't get rid of them. what do you do with people like that? any suggestions on how to love the unlovable? How do you get to be the last pistacio thrower?
