DON'T JUMP OFF THE ROOF DAD as sung by Tommy Cooper - 1961


VERSE: Daddy came home from work tired.
The boss had been driving him mad.
The kids started fightin'. The dog bit him too.
His dinner was nothing but warmed-over stew.
I guess it was then he decided
Up to the rooftop he'll go.
He was about to jump off when
The kids started howlin' below: "Oh—

CHORUS: Don't jump off the roof, Dad.
You'll make a hole in the yard.
Mother just planted petunias.
The weedin' and seedin' was hard.

Won't you please give us a break?
Just take a walk to the park, Dad,
And there you can jump in the lake.
