I have never heard of this, though I would suggest that in a vaguely similar vein you might like Stephen Fry's The Liar better.
Unreliable Narrator tropes are such fun. I just came across a DELIGHTFUL example of it in The Somnambulist. My favourite example from that book involved a lengthy scene in which a previously unsympathetic villain character is poisoned, realizes what has happened, suffers the slow torment of his inevitable death as he returns home to bid his farewells to his small crippled child whose mother died tragically some years before, and it's all very touching, and then the Narrator breaks from the story to chat with the reader (this happens fairly often) and says, more or less, "LOL no seriously that was total bullshit. Did you cry? I bet you did. Ain't I a stinker? Now back to our regularly scheduled series of murders, time-travelling Gods, and disfigured prostitutes..."
