When in the Girl Guides (1950's) we sang:-

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 to pray for your soul,
Ha ha ha, hee hee hee
How happy we shall be.
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.
etc etc.
I don't think this would go down well with today's 'snowflakes' eh?
