It's not fit to print, but Sarah Silverman just made the most shocking "Paris Hilton Goes To Jail" joke at the MTV Movie Awards with Paris Hilton sitting in the audience. [Edit: Actual screen shot above.] At the moment the cameras cut to Paris, it might qualify as the most uncomfortable moment in the history of TV ever.
I'll wait for the YouTube.Com clip to link (but I think MTV might be owned by Viacom which means there won't be any YouTube.Com clips.)
Edit: Thanks to a buddy for texting me that the video can be found here.
