George wasn't at the golf course like he said he was but rather was schtooping his neighbor's wife.
a short little dude who is obviously a beast and gets all the ladies. He gets straight A's but still couldn't get you something off the top shelf. Ask him about anything, even say hi to him and he'll tear you to shreds because he's vicious. Overall you pretty much wanna have this guy on your side.
