To discourage graffiti in the bathroom stalls at school, there is a large piece of posterboard attached to the wall of each stall. Generally, the things written there make for very...interesting reading. Yesterday, I saw something that made me laugh, and reinforced the fact that brevity is the soul of wit:

Be kind to animals.
They are our brothers and sisters
in furry and feathered coats.

Do not eat them.
Do not wear them.
Do not hurt them.

And then, written underneath, simply:

I like steak.
