Mastermind

I have always felt as though Mastermind felt like some variation of another game show idea named "Expert or Liar" which was featured in the eponymous Regular Show episode. What I mean by that is that, just like in Expert or Liar, the contestants in Mastermind choose a very niche subject to have asked questions on, and that subject is also something the contestants almost always claim to be an "expert" in said subject.

Though I guess it's rather boring by comparison, since the contestants come on this show on their own will, and don't get humiliated if they get a single question (of a subject they claim to be an expert in) wrong.

Anyway, if you liked that episode of Regular Show, this show might be worth taking a bit of a look at.
