Who talks more?
 

A husband, proving to his wife that women talk more than men, showed her a study which indicated that men use (on the average) only 15,000 words a day, whereas women use 30,000 words a day.
She thought about this for a while and then told her husband that women use twice as many words as men because they have to repeat everything they say.
Looking stunned, he said, "What?"
