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

"No woman," said one man, scornfully, "can keep a secret."

"I don't know about that," huffily answered a 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 lady. "When a woman has kept a secret for twenty-seven years, she can keep it forever."

So that's four score and eight then.
