(Thanks Tom!) From The Arrogant Worms:

I am cow
hear me moo-
I weight twice as much as you-
and I look good on the barbecue

yogurt curd cream cheese and butter’s-
made from liquid from my udders
I am cow
I am cow
hear me moo

I am cow
eating grass
methane gas comes out my ass-
and out my muzzle when I belch
Oh the ozone layer’s thinner-
from the outcome of my dinner
I am cow
I am cow
I’ve got gas

I am cow
here I stand-
far and wide upon this land-
and I am living everywhere
from B.C. to Newfoundland-
you can squeeze my teats by hand
I am cow
I am cow
I am COW

I am cow
I am cow
I am cowwwwwwww
