The first episode of this season (Season 2, Episode 1) found me laughing several times as I realized I was watching a little kid who learned a new curse word. The use of the "f" word seemed so forced and unnatural. After going a whole season, watching these people never so much as let a "darn" pass their lips, they suddenly start throwing scat like an angry monkey, and engaging in verbal fornication. Hot tip to future shows that get the go ahead to start cursing after establishing characters for a whole season: ease into it, rather than going nuts with it. Otherwise, everyone on the show is suddenly breaking character.
Great show overall.
