Lecture Tour with A Difference

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 policeman.  ‘What are you doing out here at four o’clock in the morning?’ asked the police officer.

‘I’m on my way to a lecture,’ answered Roger.

‘And who on earth, in their right mind, is going to give a lecture at this time on New Year’s Eve?’ enquired the constable sarcastically.

‘My wife,’ slurred Daniel grimly.
