Joke

Two men Tom and Paul are chatting as they work.

Tom says: "I've been attending night classes for 5 months now and I have an exam next week."

Paul: "Ooh!"

Tom: "For example, do you know who is Graham Bell?"

Paul: "No."

Tom: "He's the inventor of the phone in 1876. If you take night courses you would know this."

The next day, the same discussion took place.

Paul: "Do you know who Alexander Dumas is?"

Tom: "No."

Paul: "He's the author of 'The 3 Musketeers'! If you take night courses, you would know this."

The next day, once again:

Tom: "And do you know who Jean Jacques Rousseau is?"

Paul: "No"

Tom: "He's the author of 'Confessions', if you take night courses, you would know this."

This time, Paul got irritated and said: "And you, do you know who John Smith is?"

Paul: "No"

Tom: "He's the guy roaming with your wife! If you stop night courses, you would know!"
