An old couple is sitting in their living room when the old woman leans over and says to the old man, "Remember when we were younger and you used to hold my hand?"

The old man grabs the old woman's hand.

Then she says, "Remember when we were younger and you used to put your arm around me?"

The old man puts his arm around the old woman.

Then she says, "Remember when we were younger and you used to nibble on my ear?"

To the old woman's surprise, the old man gets up off the couch and starts to walk away. "Honey, where are you going?" she says.

The old man replies, "I'm going to get my dentures."
