Apparently, it's okay to use the word "fuck" on live television as long as you don't mean it literally:

[T]he Federal Communications Commission … ruled without fanfare Friday that it's OK to use that word (for which we will substitute "feep") as long as you're not being literal. Follow the logical bouncing ball: You can say "feep" or "feeping" if you don't really mean "to feep."

Now, whether or not you think the 7 dirty words should be prohibited on-air or not, I think you pretty much have to admit that this ruling is truly fucked up.
