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 *** 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 bed It's just B I O L O G Y

Can't you see? It's just biology

Biology, coming in between you and me Your 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 tails Which 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 brain It's nothing to do with their hearts

Nothing to do with their heads

Nothing to do with their home

Nothing to do with their beds It's just B I O L O G Y

Can't you see? It's just biology

Biology, coming in between you and me She 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 James I 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 bed It's just B I O L O G Y

Can't you see? It's just biology

Biology, coming in between you and me
