A man was an in-patient in the City Hospital.

He sneaked out of the Hospital down to Shaftesbury Square and into Lavery's pub
still in his dressing gown.

He ordered a pint of Smithwick's and a double Black Bush.

Having downed them in 5 minutes he asked for the same again.

As he drained the last drops of the Bush he said to the barman,
"I shouldn't be drinking this with what I've got."

The barman stood back, alarmed, and asked "What have you got?"

"About 50p" said the patient.
