Continuity mistake: When the men are in the lounge room, one of them is playing GTA III on a PS2. Note the car he is in (a squad car) and the health (a heart logo near it with 68). Pattie enters room and says goodbye. The men try to figure out who slept with her. On figuring it out they jump up and leave room, we get one more shot of the game and he is now in a different car and health is 100. You will notice that he doesn't play it long enough to change cars as he is not looking at the screen long enough. During the scene you can hear the sirens of the squad car he was in, meaning he didn't change cars. Also he never would of regained full health that quick.
