When you know you're having your last interview with David Letterman as host of "The Late Show," you obviously want to go out with a bang.
Comedian and Peabody Award winner Amy Schumer made the most of her late-night appearance on Monday after telling an anecdote from the MTV Movie Awards about how she always says the wrong thing to celebrities. Letterman basically gave her carte blanche by saying, "Since we probably won't be on the show together again, do something now that you'll regret."
Without missing a beat, Schumer gets up to show the audience her surfing scar, otherwise known as her "vagina," at least for the purposes of this bit. Watch the clip to see how fast Letterman's face turns red.
