Three sisters were getting married within a short period, and their mother, feeling a bit concerned about their honeymoon experiences, made them promise to send a postcard with just a few words describing how their marital intimacy was going.

A few days after the first daughter’s wedding, a postcard arrived from Hawaii. It had just one word: “Nescafé.” Perplexed, Mom went to the kitchen, grabbed the Nescafé jar, and read the label: “Good till the last drop.” She turned red but was happy for her daughter.

A week later, the second daughter’s postcard arrived from Vermont. It read: “Benson & Hedges.” This time, Mom went straight to her husband’s cigarette pack and read: “Extra Long, King Size.” She blushed again but felt relieved.

The third daughter left for the Caribbean, but no postcard came. A week passed, then two, then a whole month. Finally, a postcard arrived with shaky handwriting that simply said: “British Airways.”

Panicked, Mom flipped through her Harper’s Bazaar magazine, searching for the airline’s latest ad. When she found it, her eyes widened, and she fainted.

The ad read: “Three times a day, seven days a week, both ways.”
