The show was called Bulls**t (replace the ** with the actual letters) and ran on Showtime for 6 or 8 seasons. I have them all on DVD and even though the series was cancelled over 10 years ago, it still holds up today.
Oh I know what it was. Just it was VERY X-rated.
Too bad they couldn’t just stick with the actual subject than having naked guys and girls around all the time, never mind the cussing!
