At a dinner party, several guests were arguing whether men or women were more trustworthy.

"Not woman", said one man scornfully, "can keep a secret"

"I don't know about that", answered a blonde woman guest. "I have kept my age a secret since I was twenty-one"

"You'll let it out some day", the man insisted.

"I hardly think so", responded the blonde lady. "When a woman has kept a secret for twety-seven years, she can keep it forever"
