Head on Curb

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" and scratchs 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. "Head on curb."
