David Letterman couldn’t keep his old chap in his trousers around various interns and got blackmailed about it and it was all very unpleasant. However, cheating on your wife is nothing compared to the damage done to American thinking by Fox News and a chap called Andrew Breitbart who recently were on the receiving end of a rather sweary and fiery diatribe from the talk-show host.

In a show that saw Letterman interviewing Rachel Maddow (who is, for the record, a really splendid human) on the Late Show, they got round to discussion important stuff. Of course, hecklerspray doesn’t normally cover The Big Issues, but these issues have swear words in them, so we’re cool.

Over the jump is a video of Letterman uncharacteristically swearing and getting very political and, to be perfectly frank, it makes for some very, very good television.

Unless you work for Fox or are a frightened white conservative.

In the segment, whilst railing against political bias or whatnot, Letterman spits:

“How much time was wasted by this asshole fucking around?”

This “asshole” is Andrew Breitbart who is paid to get news coverage and edit it in such a way that it says the complete opposite of what it intended.
