One bright day in the middle of the night
Two dead boys went out to fight
Back to back they faced each other
Drew their swords and shot each other
A deaf policeman heard that noise
He came and killed those two dead boys

I find the variations of the Two Dead Boys poem fascinating. Everyone who knows it knows a slightly different version, and it changes as it gets passed along (like traditional folk songs and poems - The Three Ravens/Twa Corbies is another one that interests me).
I’ve since added the lines “If you don’t believe this lie is true / Ask the blind man, he saw it too” to the end, after picking them up from other people’s versions.

I stand before you to sit behind you to tell you something I know nothing about.
There will be a gentlemen’s meeting for ladies only, so wear your best clothes if you have none.
Free admission, pay at the door; great seats, right on the floor!

I’m probably not remembering this right, but I’ve seen it as both a separate rhyme and as part of the Two Dead Boys.
