I don't know how many of you have seen this before, but my grandpa just sent it to me. I had read it along time ago and forgot how funny it is.
A herd of buffalo can move only as fast as the slowest buffalo. When predators approach the herd, 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 as a unit can only operate as fast as the slowest brain cells. Excessive intake of alcohol, we all know, 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. That's why you always feel smarter after a few beers.
