Now I know why you're so smart
I am sure you'll love this theory...
 A herd of buffalo can move only 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 attrition of the weakest members.
In much the same way the human brain 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.
