An elderly married couple enters a restaurant for dinner and orders some food. As the waiter serves the food on their table, the husband starts eating while the wife just looks at her platter.

Astonished by this rather unusual scene, a young man sitting besides goes over to their table and courteously asks the lady as to why is she only staring at but not eating her food, The women agreeably replies, "Well son, we have only one set of dentures and today it's his turn first."
