A sheep grows wool and is quite dumb
a lamb becomes a sheep.
Small numbers swell into a sum
sum totals are to keep.
A boy sprouts hair and soon grows tall
a man was once a boy,
all men predictably will fall
like a discarded toy.
Philosophies they come and go
take over silly minds,
it's not the whom but what they know,
it's all in their behinds.
Reinhard Stobbe
