Yeah, it definitely ranges with them. Like ArcturusOne mentioned, I would feel comfortable rewatching the recent BG&EHD playthrough, but MGS has a healthy amount of ribald material. If they can wear headphones, then I can only think of one visual gag that would be unsavory to a conservative work environment.
The Cabela LP is from Chip and Ironicus as well. But I concur with the statement that they can get a bit ribald, but the majority of their stuff isn’t. They make superb background noise.
