All of the ten members of the Board of Directors of the company were called into chairman's office one by one until only Bob, the junior member, was left sitting outside.
Finally it was his turn to be summoned. He entered the office to find the chairman and the ten other directors seated around a table. He was invited to join them, which he did.
As soon as he had sat down the chairman turned to Bob looking him squarely in the eye, and with a stern voice, asked, “Have you ever had sex with Mrs. Foyt, my secretary?”
“Oh, no Sir, positively not!” Bob replied.
“Are you absolutely sure?” asked the chairman.
“Honest, I’ve never been close enough to even touch her!”
“You’d swear to that?”
“Yes, I swear I've never had sex with Mrs. Foyt anytime, anywhere.”
Good, then you fire her!
