I, personally, do not take IQ tests seriously.
I find it hard to believe that one can quantify intellect, especially by taking a single (usually static) quiz.
Back on topic of the game, though, I feel that the "humor" in the game is too nonsensical for my taste (sure, some degree of randomness in humor is fine, but it must be cohesive; the game simply ties together a bunch of attempts at forcing out a giggle), and the game itself only conveys this "humor" through annoying mechanisms such as forcing the player to guess the blatantly wrong answers.
