The bill reads as follows (go to Thomas, type in "H.R. 3687" if you doubt me):
A BILL To amend section 1464 of title 18, United States Code, to provide for the punishment of certain profane broadcasts, and for other purposes.
Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled, That section 1464 of title 18, United States Code, is amended--
(1) by inserting `(a)' before `Whoever'; and
(2) by adding at the end the following:
`(b) As used in this section, the term `profane', used with respect to language, includes the words `shit', `piss', `fuck', `cunt', `asshole', and the phrases `cock sucker', `mother fucker', and `ass hole', compound use (including hyphenated compounds) of such words and phrases with each other or with other words or phrases, and other grammatical forms of such words and phrases (including verb, adjective, gerund, participle, and infinitive forms).'.
Still legal to say on the radio: "blowjob", "dickwad", "rimming", "santorum" and "big floppy donkey dick".
