"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."
