A businessman and his secretary, who were overcome by passion, went to his house for an early afternoon quickie.
“Don’t worry”, he assured her, “my wife is out of town on a business trip, so there’s no risk of us getting caught”.
As one thing lead to another, the secretary reached into her purse and suddenly gasped, “We have to stop! I forgot to bring birth control!”
“No problem”, the businessman replied, “I’ll just get my wife’s diaphragm”.
After a few minutes of searching, he returned to the bedroom in a fury.
“That witch!” he exclaimed. “She took it with her! I always knew she didn’t trust me!”
