The Stone Age.

(Air: "There you are, then.")

Oh, the Stone Age,
The rag and bone Age,
Manhood's own age,
The age to woo.
Don't take your girlie to a show,
Just knock her on the head if she declines to go.
If she coquets,
Don't fling bouquets,
Biff some brickbats
And beat her blue.
Say "Liza, I luv yer" as you give her neck a screw,
In the Stone Age,
That's what you do.
(Repeat.)
