A man walks into a pub in a hospital gown, carrying a drip behind him.
'Oh, poor you!' said the barman. 'What can I get you?'
He asks for a Scotch. The barman brings it over and the man downs it in one.
'I shouldn't be drinking this with what I've got,' the man says.
'Oh I'm sorry. What have you got?' asked the concerned barman.
'50p.'
