Before Foggy met Matt he did a porn film. Matt hears it one day at college playing in a classmates dorm room. He means to tell Foggy but… how would he explain that he heard it? The problem is now his brain has made the connection between Foggy and sex, everything Foggy does sounds pornographic. Also Matt really, really needs to find out exactly what Foggy was doing on the video but he doesn’t have a copy and even if he did it’s not like he can ask someone to watch it with him and he’d going to go ahead a assume it doesn’t have audio description.
Matt/Foggy, Foggy has done porn films in the past.
