Are there really only seven words you cannot say on television (or radio) in the US? What aren’t you allowed to say?
ANSWER PERSON RESPONDS: No, there are a lot more. The seven just comes from a famous 1973 George Carlin monologue. See the wikipedia entry on “Seven Dirty Words”: http://en.wikipedia.org/wiki/Seven_dirty_words or “F.C.C. v. Pacifica Foundation”: http://en.wikipedia.org/wiki/F.C.C._v._Pacifica_Foundation
You will find listed there those seven words, as well as a discussion of other bad words, or just do a sloppy Google search. One or two of the seven seem to be OK today, even on broadcast TV.
For a dry discussion of this, you can see the famous 1978 Supreme Court decision, 438 U.S. 726: http://caselaw.lp.findlaw.com/scripts/getcase.pl?court=US&vol=438&invol=726
