An old derilict cuss is hospitalized for some tests after being found unconscious on the city streets.
The morning of the second day of his visit, one of his young nurses aids walks in with a glass jar in her hand.

"Good Morning, Mr. Jones, I need some urine today," she says.

The old man gives her a big toothless grin and winks, "I been wantin some of your'n too but I was afraid to ask."
