The flower vendor was an old hand at unloading his last few bunches. Appealing to a businessman on his way home, the vendor said, "How about a nice bunch of roses to surprise your wife?"

"Haven't got a wife," responded the businessman gruffly.

"Then how about some carnations for your girlfriend?" proposed the vendor without missing a beat.

"Haven't got a girlfriend."

"You lucky guy!" The vendor broke into a big smile. "Buy both bunches to celebrate!"
