Here's another song I know of. NOTE: All animal lovers, discontinue reading NOW! First and last three words in verses are slower.

We've got an animal liberationist in our lab,
In a cage behind the storage shelves in room one-seventeen.
He helps with our experiments, although he'd rather not,
But think of all the rodents that he's saving from those shots.
His cause was true, his heart was pure. He'd better hope we find the cure.

You see, we had a little warning, threatening calls, and letters too.
We prepared a nice surprise with springs and chicken wire and glue.
When he came creeping in that night, he didn't see our trap,
Until he tripped the lever and the cage door came down SNAP!
'Twas such a noble sacrifice to give himself to save those mice.

We've said we'll let him out as soon as we can cure what he has caught.
You can bet he's learned you shouldn't open lab doors labeled "Hot".
Now with a human subject, our results are up ten-fold,
Although sometimes our testing gets a little uncontrolled.
We could do so much with three or four; perhaps someday we'll get some more.

We've got an animal liberationist in our lab,
We feed him only certified Pureena Human Chow.
Although we are quite proud of him, we keep him hid away,
Especially when inspected by the U.S. D of A.
Though he may cry, "Alas, alack!", I don't think we'll send him back.
