Oh dear - I tried getting my Dad to play Halo 2 with me once - and only once. The only embarassing thing was how bad he was - I think he's got that mental block you were talking about G3oFF. No matter how many times I told him to 'look where you're running!' he consistantly ending up looking at either ceiling or floor, and not anything between. It was sad and painful, and a day to be forgotten by all.
