There are hundreds of versions of this, but this is the one I heard as a child.
One fine day in the middle of the night,
Two dead men got up to fight,
Back to back they faced each other,
Drew their swords and shot each other.
A deaf policeman heard the noise,
And came and killed those two dead boys.
If you don't believe this lie is true,
Ask the blind man, he saw it too.
