Believe it or not, we sang something very similar to this in the Girl Guides!

Whenever you see a hearse go by
Remember that you are going to die.
Ha ha ha, hee hee hee, how happy we shall be!
They put you in a deep dark hole,
Then go away and pray for your soul.
Ha ha ha (Chorus)
The worms crawl in and the worms crawl out
They crawl in thin and they crawl out stout.
(Chorus)
Your eyes fall in and your teeth fall out.
Your brain comes trickling down your snout.
(Chorus)
(First line repeated, end of song)

Imagine today's children being encouraged to sing such a ghoulish song! But we thought it was very funny and loved it.
