On the subject of cows:

Wandering through the world of mirth,
Finding nothing of real worth -
save the spacious greeny grass.

Simplistic view of endless life,
saved from all the futile strife -
mindless of the killing gas.

Expurgiated.  Killing man.
Who cares?  They don't.
While environment'lists ban,
they go on using the can.

Going on through life,
mindless of the endless strife,
Then they die,
though never cry.
