Meet your latest YouTube meme: David Letterman's Late Show interview with Paris Hilton. On Friday, the talk show host had Hilton as the guest of honor... and set her image rehab effort back about five years. Not that making Paris Hilton looks bad takes any particularly hard work, but Letterman made sure viewers wouldn't forget about her jail stint. Mainly because that's the only thing he would talk about.

Expect to see this clip on about 500 other blogs in the days to follow.
