“You’re very beautiful,” the boss said to the new secretary.  “I’ll bet a lot of men ask you for dates.”

The girl smiled sweetly and replied, “Yes, but I don’t go out with anyone I find unattractive.  I let them down nicely by telling them I’m married.”

The boss nodded.  “That makes sense.  Say, are you busy Saturday night?”

“Yes,” she answered, “I’m getting married.”
