    There are 3 doors, behind which are two goats and a car.

    You pick a door (call it door A). You’re hoping for the car of course.

    The game show host, examines the other doors (B & C) and always opens one of them with a goat (Both doors might have goats; he’ll randomly pick one to open)

    Question: Do you stick with door A (original guess) or switch to the other unopened door? Does it matter?

    Poll to follow.

    What would you do? 30 votes

    Stick with door A because it'll increase my chances of winning the car

    Switch to the other unopened door because it'll increase my chances of winning the car

    What if you actually want a goat; will it be a good looking goat?

    Only if it's an older goat.

    Can we have another poll to see if the first poll was more relevant:
    A: before Gordon gave the answer
    B: after Gordon gave the answer

    Another mind fcuk.

    Why is there no poll option for I want a goat.

    Why is there no poll option for Atari Jaguar.

    Please fix poll.

    You leave the game show host there, take the goat, and go through the second door.
    If it's another goat, swap the goats and continue through the third door.
    Take the car, put the goat in it.
    Go back through the first door, drop the goat back, collect the game show host and .... wait, that's a different problem.

    Probably a pun.

    Based on your use of probably instead of probability.

    It sucks when you explain a joke.
