(In one episode of 'Cheers", Cliff is seated at the bar describing the Buffalo Theory to his buddy, Norm)
"Well you see Norm, its like this...A herd of buffalo can only move as fast as the slowest buffalo. And when the herd is hunted, its 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 alcohol eliminates the weaker brain cells, thus making the brain a faster, more efficient machine. And that Norm, is why you feel smarter after a few beers."
