According to TVGuide.com, David Letterman’s lame joke about Alaska Governor Sarah Palin and one of her daughters has prompted the Embassy Suites hotel chain to pull its advertising from the CBS website. The Hilton Hotels Corp subsidiary told the media outlet it did so because: “We received lots of e-mails from concerned guests We assessed that the statement that he made was offensive enough to our guests and prospective guests that we elected to take the ads down.” Embassy Suites isn’t an advertiser on Letterman’s Late Show or it would have pulled its commercials there, too. Dave has apologized. But many think that Letterman’s ratings have risen as a result of all the publicity, and that’s no joke.
