VIDEO: Jason Segel, John Krasinski, Alison Brie, and Emily Blunt Kill Some Karaoke Standards

Jason Segel, Alison Brie, and Emily Blunt -- three of the stars of the upcoming Five-Year Engagement -- and some silly television star named John Krasinski convened off set, crashed an Ann Arbor bachelorette party, and howled karaoke standards to the delight of all YouTubia. Who wins this duel: Segel and Krasinski with their rendition of "With a Little Help from My Friends," or Brie and Blunt with "Total Eclipse of the Heart"? Video follows.

Based on sheer commitment level, the victory goes to Blunt and Brie. But where's video of Krasinski and Blunt crooning together to "Islands in the Stream" or "Cruisin'"? Enlighten me, karaoke gods!
