You just gotta shake your head at a guy like that. I used to play with a friend who always lied on his scorecard when we played. Since he was my friend I didn't want call him out on it at first because if he got mad it would just ruin the whole round. After a couple rounds I asked him what his hanicap was and his response was, "I am usually a +1.2, but I am just in a slump lately." I called him out on that and said "Bull$hit" and haven't played with him since because it is frustrating to play with someone who can't even be honest. And i gotta say it has been more fun without him :)
