Enforced Method Acting: The panellists have never seen what is on the card before they read from it - all of the lies must have their details made up on the spot.note In the case of the truths, the panellists have a meeting with the producers before the show and write down a couple of truths so they can generally expect what might show up there.
Old Shame: Nick Hewer regrets his appearance in this programme, and claims he has never felt more embarrassed. Of course, his attempts to maintain his trademark sternness led a masterfully Comically Serious performance.
Screwed by the Network: The show has not been scheduled consistently for two series running. Just when it looked like things might be improving with series 5, the BBC inexplicably decided to dump series 6 in an awful pre-watershed timeslot in the Spring with no promotion. (To add insult to injury, the last episode went missing for a month due to Euro 2012 and a filler documentary about the Queen's jubilee.)
The buttons the panellists press to (supposedly) bring the 'TRUTH/LIE' graphics up on screen aren't actually connected to anything and are purely for effect (as shown in a few out-takes where the panellists forget to push the button but the graphics come up anyway, or they do press the buttons but nothing happens).
