A businessman and his secretary, overcome by passion, retire to his house for what is popularly termed a "nooner." "Dont worry," he purrs. "My wife is out of town on a business trip, theres no risk."
As one thing leads to another, the woman reaches into her purse and suddenly gasps, "We have to stop, I forgot to bring birth control!"
"No problem," her lover replies. "Ill get my wifes diaphragm." After a few minutes of searching, he returns to the bedroom in a fury.
"That witch!" he exclaims. "She took it with her! I always knew she didnt trust me!"
