A woman had three daughters getting married the same day. Naturally she was worried about their sex life. It was agreed that they would send a discrete message.

Two weeks after the triple wedding the first message arrives. An ad for Maxwell House with the slogan "Good till the last drop." She's happy for her girl.

A month passes and a second message arrives with a Marlboro ad. "Marlboro: Extra long, extra strong." She's a little embarrassed, but happy.

Three months pass. She's really worried about her youngest when finally a message arrives. It's addressed in shaky handwriting and contains an ad for British Airways. "London to Paris: Seven days a week, three times a day, both ways."

She fainted.
