There's no joke; the 4th choice (in addition to 25%, 25%, 50%) is arbitrary; it could be 0%, 100%, or anything other than 25% or 50%. The only purpose it serves is to be a 4th option (thus making the probability of choosing any individual answer 25% when choosing randomly).

The question would work just as well if it had 3 options:

1/3, 1/3, 2/3.

I think having 0% as the 4th choice would have actually made it more interesting.
