Can someone explain if the situation in the logician joke really works?
I know it works if it's about wearing colored hats.
Let's say they are all wearing hats but don't know the color. If the beekeeper is blind and asks "are you all wearing yellow hats?" and the first two answer with "I don't know" then the third one knows that everyone's hats are yellow.
But the question "does everyone want beer" can not be resolved like this. So the joke is even a play on another joke.
