Lyrics

Well, I know it can feel like a prison
In a maze of law and taboo,
Not the least of which dealing with matters
Of how one disposes of poo,
But thinking ourselves above nature,
We hide from our instincts, denying it's true
That this business called 'civilization'
In its essence no more amounts to...

Flinging poo at the zoo (x2)
Express your point of view
Flinging poo at the zoo.
Try to prove it's a lie and I'll show you a guy
Who's flinging poo at the zoo.

Can you imagine being a monkey
Hanging out with nothing to do
On display inside your cage
With your keeper studying you?
Would you possibly savor returning the favor
By flinging poo at the zoo?

Flinging poo at the zoo (x2)
Express your point of view
Flinging poo at the zoo.
Try to prove it's a lie and I'll show you a guy
Who's flinging poo at the zoo.

Do you imagine you are a human
With a relatively high IQ?
If you're so smart, then tell me
Why don't you do what you wanna do?
If you're so free, why are you charged a fee
For flinging poo at the zoo?

Flinging poo at the zoo (x2)
Express your point of view
Flinging poo at the zoo.
Try to prove it's a lie and I'll show you a guy
Who's flinging poo at the zoo.

Well, the medicine man with the glove on his hand
Loves flinging poo at the zoo
Them soldier boys with the killer toys
Are flinging poo at the zoo
As the gal on the news gets the scoop on who's
Flinging poo at the zoo.

Flinging poo at the zoo (x2)
Express your point of view
Flinging poo at the zoo.
Try to prove it's a lie and I'll show you a guy
Who's flinging poo at the zoo.

Now you may say, "Ahem, Doctor Sparkles,
We are people and not in a zoo,
So we shouldn't be likened to monkeys
Who sit around flinging their poo.
And you may say, "It takes one to know one.
You're the one with the potty mouth singing of poo."
And to this I have no smart rebuttal,
So I'll just carry the metaphor through.

Flinging poo at the zoo (x2)
Express my point of view
Flinging poo at the zoo.
Try to prove it's a lie and I'll show you a guy
Who's flinging poo at the zoo.

Pig squeals the siren,
Cock preaches the word,
Ass calls for order,
Cat growls, "Freebird!",
Seal gives approval,
Spider makes the kill,
Squirrel buries the stash,
Duck brings the bill.

Whatever your means or genetic leanings
For flinging poo at the zoo,
Wherever you're jailed you can grow a tail
For flinging poo at the zoo.
However you find to speak your mind
To flinging poo at the zoo,
Mine your emission for ammunition
For flinging poo at the zoo.

Flinging poo at the zoo (x2)
Express your point of view.
Look out! That's flying poo.
Now throw you a poo poo,
For you do that doo doo so well.
