what how

There are only four kinds of people in this world

Cretins, Fools, Morons and Lunatics

Some carry hammers, others sticks

either way, they are pretty scary

Oh, and some are bold, others hairy.

 

There are also only two kinds of animals

Warm blooded animals and ticks

One sucks at having a conscience, the other sucks

Just like you and me

 

And finally there is only one type of tree

The one that sucks the earth until it is chopped by a man,

killed by a lightning or an elephant's trunk

No tree can run.
