Standard (EADGBE)

Verse 1

Glass of milk, standing in between extinction in the cold

 And explosive radiating growth.

 So the warm blood flows

 Through the large four-chambered heart,

Chorus

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

Bridge

Verse 2

 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

Chorus

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

Bridge

Placental the sister of her brother Marsupial

Their cousin called Monotreme

 Dead uncle Allotheria

Chorus

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
