“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
drinking 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.”
