There are many diseases,
That strike people's kneeses,
Scorflufus! is one by name
It comes from the East
Packed in bladders of yeast
So the Chinese must take half the blame.

There's a case in the files
Of Sir Barrington-Pyles
While hunting a fox one day
Shot up in the air
And remained hanging there!
While the hairs on his socks turned grey!

Aye!Scorflufus had struck!
At man, beast, and duck.
And the knees of the world went Bong!
Some knees went Ping!
Other knees turned to string
From Balham to old Hong Kong.

Should you hold your life dear,
Then the remedy's clear,
If you're offered some yeast - don't eat it!
Turn the offer down flat-
Don your travelling hat-
Put an egg in your boot - and beat it!
