I have recently re-watched the entire series and enjoyed it as much the second time as I did the first. The whole cast is great but John McGuirk by far is the most entertaining in the show. There are so many great quotes from his character it would be impossible to remember them all but here's one of my favorites.
Coach John McGuirk: Brendon, there's nothing wrong with lying to women... or the government... or your parents... or God. Alright? Brendon Small: Yeah, but what if they figure out you're a liar? Coach John McGuirk: What, women? Brendon Small: Sure. Coach John McGuirk: Then who needs 'em? Lie to men.
