Last night, all three Kardashians visited The Late Show to share Kim's butt x-ray with David Letterman. Tensions were thick when Khloe insulted Kim, but it was nothing that Kourtney's meaningless exclamations couldn't resolve.
Denis Leary joined Jimmy Fallon on Late Night to hint at a few pretty big spoilers about the Rescue Me series finale. Seriously, this is probably not stuff he should be saying on television.
Also on Late Night, Olivia Munn reminisced on her mother's frequent beatings (complete with heavily stereotypical Asian accents).
Finally, Weeds' Kevin Nealon visited Conan to address his fears of sharks and chimpanzees (describing in thorough detail how these animal attacks would play out), and his longtime dream of being chased by the cops.
