A policeman is on scene at a terrible accident - body parts everywhere. He is making his notes of where the pieces are and comes across a head. He writes in his notebook: "Head on bullevard."
He then scratches out his spelling error. "Head on bouelevard." Nope, doesn't look right - scratch scratch.
"Head on boolevard..." dang it! Scratch, scratch.
He looks around and sees that no one is looking at him as he kicks the head. Back to his notepad, he writes, "Head on curb."
