There are many swears that have started to make their way on to television, and I don't mean just HBO and Showtime. I've heard "shit" and "asshole" sprinkled here and there.
But there's still one word that's a no-no, and that's the famous four letter word that begins with the letter "F." It's banned on network television, and I think even on cable you can only get away with it so many times during one show. In the movies there are limits to the number of times it is used and the context (exclamation or verb?).
After the jump are the top ten videos of the word being used on live television. This Digg post lists the Richard Simmons clip as number one, but that's not accurate because they're outtakes, not live segments. Still funny though!
