The original joke:

An old Irishman shuffles into a bar at sundown with his eyes low and his head down.

The bartender says: “Ay, Billy! What’s the matter? You seem troubled.”

Billy responds: “You see this bar we’re standing in? I built it with me own hands! But they don’t call me the bar builder, no!”

“And the bridge everyone uses to cross the river to get to the market, I built that with me own hands too! But do the call me the bridge builder? No, they do not.”

“And the wall that protects our city, I built that with me own hands too! And they don’t call me the wall builder neither.”

“BUT YOU FUCK ONE SHEEP!…”
