Two little birdies

Sitting on a hill

One named Jack 

And one named Jill

Then came along Bill

Jack, Jill and Bill

Were a trio

Then became the duo without Jill

Jack didn’t know

That Jill felt like this, because of Bill

Jack and bill 

Two peas in a pod

Always a thrill

Jill always felt odd

All thanks to Bill

Two little birdies sitting on a hill

One named Jack and one named Bill

Fly away Jack, fly away Bill

Come back Jack and come back Bill

Goodbye Jill

A third extra wheel

A third extra nostril

A third extra ear

They don’t exist here

Jill all alone

Walking into the unknown

Jack and Bill plus Jill

Equals Jack and Bill minus Jill.
