Cliff Claven “Beer Theory” ,from the show “Cheers”

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 heard 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
