Priest is walking through his parish, one of the hard-bitten sections of town. Pretty woman on the corner calls out to him, “Head, 10 bucks.” He smiles politely, walks on, ruminates.
When he gets back to the cathedral he’s still thinking it over. Walking through the garden, he comes upon one of the nuns and asks, “Sister, what’s ‘head’?”
She replies, “Same as downtown, 10 bucks.”
