'The Unbelievable Truth' is a comedy show on BBC Radio 4.
The premise is to read a pre-prepared list of statements (only 5 of them are factual) on a subject. The reader gets a point for every true statement smuggled past the other contestants. If one of the other contestants *buzz* in and correctly identify a lie, they gain a point.
It's quit a lot like QI.
I find it's the perfect mix between information and entertainment, hitting a perfect sweet spot that many programmes lead by David Mitchell achieve.
