"MAMMAL" by They Might Be Giants
from the album Apollo 18 (1992)

Glass of milk
Standing in between extinction in the cold
and explosve radiating growth.
So the warm blood flows
Through the large four-chambered heart,
Maintaining the very high metabolism rate they have.

Mammal, mammal
Their names are called
They raise a paw
The bat, the cat
Dolphin and dog
Koala bear and hog
 
One of us might lose his hair
But you're reminded that it once was there
From the embryonic whale to the monkey with no tail.
So the warm blood flows
with the red blood cells, lacking nuclei
Through the large four-chambered heart
Maintaining the very high metabolism rate they have
Mammal, mammal
Their names are called
They raise a paw
The bat, the cat
Dolphin and dog
Koala bear and hog
Placental the sister of her brother Marsupial
Their cousin called Monotreme
Dead uncle Allotheria
 
Mammal, mammal
Their names are called
They raise a paw
The bat, the cat
Dolphin and dog
Koala bear and hog
The fox, the ox
Giraffe and shrew
Echidna, caribou
