Don’t you ever laugh as the hearse goes by,
For you may be the next to die.
They wrap you up in a big white sheet
From your head down to your feet.
They put you in a big black box
And cover you up with dirt and rocks.
And all goes well for about a week,
Until your coffin begins to leak.

And the worms crawl in, the worms crawl out,
The worms play pinochle on your scalp,
They eat your eyes, they eat your nose,
They eat the jelly between your toes.

A big green worm with rolling eyes
Crawls in your stomach and out your sides.
Your stomach turns a slimy green,
And pus comes out like whipping cream.
You spread it on a slice of bread,
And that’s what you eat when you are dead.

And the worms crawl in, the worms crawl out,
They crawl all over your dirty snout.
Your chest caves in, your eyes pop out,
And your brain turns to sauerkraut.

They invite their friends and their friends too,
They all come down to chew on you.

And this is what it is to die,
I hope you had a nice goodbye.
Did you ever think as a hearse goes by,
That you may be the next to die?
And your eyes fall out, and your teeth decay,
And that is the end of a perfect day.
