GSN Game Show where two contestants had to determine which of four Muppets was telling a lie about something in a specific category. The show ran for a mere eight episodes in Summer 2010.

"It's like Match Game with puppets...which as I say it sounds idiotic, but we think it's funny."

Larry Miller, trying to explain the show to Don Imus

The following Game Show tropes appear in Late Night Liars:
  • Bonus Round: Correctly guess eight true/false statements in two separate but comedically-overlapping categories in 43 seconds for $10,000 (or so, as the show tinkered with the amount each episode, going as high as $25,000).
  • Personnel:

Tropes used in Late Night Liars include:
  • The Alcoholic: Both the panelists and host reveled in this. They often talked about going out for drinks, and the panel (plus the contestants) had drinks sitting before them.
  • Camp Gay: William A. Mummy.
  • Hard-Drinking Party Girl: Cashmere Ramada.
  • Precious Puppy: Cashmere Ramada...or at least until she starts talking.
  • Muppets
  • No Celebrities Were Harmed: The panelists were thin parodies of existing celebs, but tended to revel in it rather than hide it.
    • Shelly Oceans --> Joan Rivers.
    • William A. Mummy --> Paul Lynde.
    • Cashmere Ramada --> Paris Hilton.
    • Sebastian Simian --> Simon Cowell.
  • Puppet Show: Uh-huh.
  • Songs in the Key of Panic: The contest music from the Bonus Round. It sped up as you went along.
  • Special Guest: On the third and fifth episodes, an actual celebrity in puppet form filled-in for one of the regulars. The fill-ins were Mickey Rourke and Rosie O'Donnell for Simian and Oceans, respectively.
  • Weasel Mascot: Weasel.
  • Upper Class Twit: Cashmere Ramada.
