Hello, I'm back again
Haven't seen you since I don't know when
It's been so long but you seem so cold
Is it something you've been told?She said, "So this is what you think of me
Going with some whore somewhere out in Germany"
I said "Baby, baby can't you see
It's nothing to do with you and me"Nothing to do with my heart
Nothing to do with my head
Nothing to do with our home
Nothnig to do with our bedIt's just B I O L O G Y
Can't you see? It's just biology
Biology, coming in between you and meYour biology lesson starts here
And first of all we should make it clear
That the species known as males
Have these little white things with little white tailsWhich multiply and start to shout
It's getting crowded down here, let us out
Once relieved they start again
It's not a process controlled by the brainIt's nothing to do with their hearts
Nothing to do with their heads
Nothing to do with their home
Nothing to do with their bedsIt's just B I O L O G Y
Can't you see? It's just biology
Biology, coming in between you and meShe said thanks, I'm so relieved
What your saying I can well believe
Now I know, I feel no shame
About Dave and Tony and Phil and JamesI said, "Baby, baby, this can't be true
She said "Well what's right for you
Has to be right for me
In any case I'm sure you'll see"It's nothing to do with our hearts
Nothing to do with our heads
Nothing to do with our home
Nothing to do with our bedIt's just B I O L O G Y
Can't you see? It's just biology
Biology, coming in between you and me
