Grandma and Grandpa were sitting in their porch rockers while watching the beautiful sunset and reminiscing about "the good old days". Grandma turned to Grandpa and said, "Honey, do you remember when we first started dating? You used to just casually reach over and take my hand?" Grandpa looked over at her, smiled and obligingly took her aged hand in his.
Growing bolder still, Grandma said, "Honey, do you remember when we were first married? You'd kind of nibble on my ear?" Grandpa slowly got up from his rocker and headed into the house. Alarmed, Grandma said, "Honey, where are you going?"
Grandpa replied, "To get my teeth!"
