A lady went to a hat shop to buy a hat. As she was very fussy, it took her a long time to pick on one.
Already at the end of his patience the salesman was afraid that she might change her mind again so he tried to flatter her: "An excellent choice, madam. You look at least ten years younger with this hat on!"
To his dismay, the lady took off her hat at once and said: "I don't want a hat that makes me look ten years older as soon as I take it off. Show me some more hats!"
