..because I @#$%-ing can.
There is an interesting CNN.com article. Americans using profanity? What?
Age of Profanity?
After I read this article I could not help but remember a woman, Ginny Foster featured on the Penn & Teller (showtime) show, BULLSHIT! - Season 2 / August 2004
She is the founder of an anti-profanity organization group called Hush-up, in which she started a website to campaign her mission to stop profanity. It appears the HUSH-UP website is no longer in service.
