On New Year's Eve, Daniel was in no shape to drive, so he sensibly left his van in the car park and walked home. As he was wobbling along, he was stopped by a police officer. 'What are you doing out here at four o'clock in the morning?' asked the officer.
'I'm on my way to a lecture,' answered Daniel.
'And who on earth, in their right mind, is going to give a lecture at this time on New Year's Eve?' enquired the police officer sarcastically.
'My wife,' slurred Daniel grimly.
