The Buffalo 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 then 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 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, more efficient machine.
And that, Norm, is why you always feel
smarter after a few beers!"
