I'm one of those curmudgeons who believes that the sitcom, as an art form (ha!), peaked in the 70's and early 80's. Barney Miller, All in the Family, M*A*S*H, Taxi and Cheers. Those were TV shows. And I think they got away a lot of stuff that probably wouldn't fly on the networks these days.
One of my favorite Barney Miller episodes was the one where the entire precinct, save Barney, got high on some funny brownies.
Here's the first third of that episode. Enjoy!
Check out the rest of the episode here and then here. It really starts to kick in that 2nd clip.
PS - New porno awfulness over at the MovieGrenade for y'all to ignore. Hit that shit!
Note: Remember to play the Bug-Eyed Trivia Challenge every day. All the stoned 70's cops are doing it.
