This was the result. (Requires Flash. Not exactly safe for work.)
It includes most of the casts of Scrubs, Six Feet Under, The West Wing, The Osbournes, Without A Trace and The O.C., as well as a bunch of other, mostly British, people I don't quite recognize. The information that was posted where I found it:
Here's the URL for an ad made for movie theaters by the UK's Channel 4,featuring some of your favorite stars whose shows appear on C4 (and probably some unfavorite ones) stating their favorite obscenities. The advertising regulatory agency said that the ad was too dirty to show in British cinemas, even though C4 was targeting it to run before showings of "Kill Bill 2." C4 says they'll air it on their E4 and FilmFour digital/satellite channels.I was deeply amused by it, at least.
