Anniversary

For their anniversary, a couple went out for a romantic dinner.

Their teenage daughters said they would fix a dessert and leave it waiting.

When they got home, they saw that the dining room table was beautifully set with china, crystal and candles; there was a note that read: "Your dessert is in the refrigerator. We are staying with friends, so go ahead and do something we wouldn't do!"

"I suppose" the husband responded dryly

Spoiler:

"we could clean the house".
