Oh, Mary had a William goat,
William goat, William goat,
Mary had a William goat,
And he was lined with zinc.

He followed her to school one day,
School one day, school one day,
He followed her to school one day,
And drank a pint of ink.

Oh, whoop-de-doo-den-doo-den-doo,
Doo-de-doo, doo-de-doo,
Whoop-de-doo-den-doo-den-doo,
Doo-de-doo-de-doo.

Oh, once he ate an oyster can,
Oyster can, oyster can,
Once he ate an oyster can,
Also a line of shirts.

The shirts can do no harm inside,
Harm inside, harm inside,
The shirts can do no harm inside,
But oh! The oyster can!

Oh, whoop-de-doo-den-doo-den-doo,
Doo-de-doo, doo-de-doo,
Whoop-de-doo-den-doo-den-doo,
Doo-de-doo-de-doo.

The can was filled with dynamite,
Dynamite, dynamite,
The can was filled with dynamite,
Which Billy thought was cheese.

He rubbed against poor Mary's chin,
Mary's chin, Mary's chin,
He rubbed against poor Mary's chin,
His deep distress to ease.

Oh, whoop-de-doo-den-doo-den-doo,
Doo-de-doo, doo-de-doo,
Whoop-de-doo-den-doo-den-doo,
Doo-de-doo-de-doo.

There was a flash of girl and goat,
Girl and goat, girl and goat
There was a flash of girl and goat
And they no more were seen.

(Slowly)
Mary's soul to Heaven went,
Heaven went, Heaven went,
Mary's soul to Heaven went,
And Billy's went to --

(Faster)
Oh, whoop-de-doo-den-doo-den-doo,
Doo-de-doo, doo-de-doo,
Whoop-de-doo-den-doo-den-doo,
And Billy's went there too.
