less calories

A husband took his young daughter to the grocery store to help him buy groceries. In addition to the healthy items on his wife's carefully-prepared list, the two of them returned home with a package of sugar-filled cookies. "Why in the world did you buy those?" his wife asked. "You know they aren't good for you!"

"Oh, but don't worry, honey, these cookies have one-third less calories than usual in them," the husband replied.

The wife looked all over the package but couldn't find any claim to that fact, so she asked, "What makes you think that?"

"We ate about a third of the box on the way home."
