Head on Bullevard

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..." Damn! Scratch scratch.

He looks around and sees that no one is looking at him as he kicks the head.

"Head on curb."
