When asked why, they say, "A little birdie told me."
Did you know they probably aren't lying? It is a little known fact that there are little birds that fly very fast, are never seen, and they are everywhere. - Thus, these creatures are called "Flies Unseen Everywhere" or FUE for short. These birds have an extensive communications network, and they can generally find out anything from anywhere quite quickly.
Some of these birds befriend certain individuals and communicate with them by making clucking sounds, much like a chicken.
They are not dumb like chickens, however, and can establish a sort of clucking language with the lucky person they befriend.
This person is then the one who is always in the know; one step ahead of the competition. And those people who seem to be in the dark? Those who just don't get it? Those who's standard response to any given question is, "Huh?"
Why I think it should be pretty obvious to all, now, that the reason is simply because they don't have a clucking FUE.
