I've heard another variant of this joke:
A friend asks a programmer if they'd like to go bowling or go to the movies.
The programmer answers: "Yes".
A friend asks a programmer if they'd like to go bowling or go to the movies.
The programmer answers: "Yes".
All three logisticians needs to be "true/yes" and the first one didn't know about the two others so the logistician says "I don't know". If he didn't wanted dessert, he would have said "no".
Same thing for the second logistician.
The last logistician was able to say "yes, we would." because none of the other logistician said "no". Therefore, they all wanted dessert.
It's Lemmy Kilminster, right?
