I was just surfing during the commercials in the football game, and in less than 20 seconds on the local CW Network channel I heard the words ass and bastard.
Are those words now appropriate for use in public? If so, I totally missed that memo.
Update: I remember the very first cuss word I heard on tv. It was on M*A*S*H. Some of the doctors went north to pick up some wounded Americans that either the NoKos or the the Chinese couldn't care for. I think it was Frank Burns who pulled out a small cigarette lighter that looked like a pistol, and one of the communists said, "What the hell is that?"
At my tender age I couldn't believe they'd use such language on tv. I wish it were still so.
