Okay, I just caught one of Greg's lies... in the episode "Iced" he said he loved cars and he acted like he had this big obsession with them, judging by that you would think that he would be interested in car magazines and stuff like. But in the episode where the three women (2 are men dressed as women) shoot up the casino (sorry I can't remember the name), Greg is reading the surf magazine and Nick tells him he should be reading car magazines, and when Nick talks about the oil that has leaked unto the pavement Greg acts like he has no clue what he is talking about and Nick starts telling Greg about how the oil turns a certain color and stuff when it's bad for the car. So with that you would think that if Greg had an obsession with cars like he said he would know this. Just thought that was interesting since we were talking about him making up stuff.
