One fine day in the middle of the night...

...two dead boys got up to fight.
(The blind man went to see fair play;
the mute man went to shout "hooray!")
Back to back they faced each other,
drew their swords and shot each other.
A deaf policeman heard the noise,
and came and killed the two dead boys.
A paralyzed donkey passing by
kicked the blind man in the eye;
knocked him through a nine-inch wall,
into a dry ditch and drowned them all.
If you don't believe this lie is true,
ask the blind man; he saw it too,
through a knothole in a wooden brick wall.
And the man with no legs walked away.
