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."
