An old one from Corky & The Juice Pigs:

White and black, the friendly bears of china
White and black, they rarely reproduce
What shall be done about these chinese bears?
What shall be done about these friendly bears?

Die, they must die
The pandas must die!
Die, they must die
The pandas must die!
Yay!

Why should we save them?
What good do they do?
Have you ever seen a panda,
Do something good for you?
They can't wear t-shirts,
They can't bounce basketballs
They can't walk tightropes,
Over niagra falls

Die, they must die
The pandas must die!
Die, they must die
The pandas must die!

(You fat bastard!)

All endangered species
Leave endangered feces
If you knew how bad they smelled
You would gladly take their pelt
If we kill them all
We can have more parking lots
We can have small couches
Made of little ocelots

Die, they must die
The pandas must die!
Die, they must die
The pandas must die!
