drunk man jokes

A doleful looking customer went to  the bar and ordered six  whiskies. The barman poured them out for him in six glasses. Now line them up in front of me, will you? Asked the customer. He then paid for them and told him to keep the change. he swallowed down the contents of the first glass in line and then repeated  the process with the third and fifth glasses. Then saying, goodnight ,’ he turned to walk away. Excuse me,’ said the barman. ‘you have left three glasses untouched.’

Yes, I know he said. The doctor said he didn’t mind me taking the odd drink.’
