A Mississippi professor was at a party and became indignant when asked if college professors were absent-minded.
‘Professors haven’t got bad memories,’ he declared. ‘They’re not absent-minded. Don’t you think I know where I am right now, and don’t you think tomorrow I’ll know where I was last night? Would somebody like to ask me another question?’
‘Yes,’ said another guest. ‘Is it true that professors are absent-minded and have bad memories?’
‘Good!’ said the professor. ‘I knew sooner or later somebody would ask me that question.’
