Cliff's Theory

(In one episode of 'Cheers', Cliff is seated at the bar
describing the Buffalo Theory to his buddy, Norm.
I don't think I've ever heard the concept explained any
better than this....)

Well you see, Norm, it's like this...A herd of buffalo
can only move as fast as the slowest buffalo. And when
the herd is hunted, it is the slowest and weakest ones
at the back that are killed first. This natural selection
is good for the herd as a whole, because the general
speed and health of the whole group keeps improving
by the regular killing of the weakest members.

In much the same way, the human brain can only operate
as fast as the slowest brain cells. Now, as we know,
excessive intake of alcohol kills brain cells. But
naturally, it attacks the slowest and weakest brain
cells first. In this way, regular consumption of beer
eliminates the weaker brain cells, making the brain
a faster and more efficient machine.

And that, Norm, is why you always feel smarter after
a few beers.
