A old man and old woman are together

An old man and an old woman are together every night.

They aren’t married, but for years and years they have spent every night together.

All they ever do is sit on the couch buck unclothed and watch TV while she holds his tool.

Every night, like clockwork, they do this sit on the couch watching TV while she holds his tool.

One night he doesn’t show up.

Then a second night goes by no show. She calls him up.

“Where you been?” “Oh … I’ve been down at what’s her name’s.” “What are you doing there?”

“Pretty much the same thing we do sitting unclothed on the couch watching TV while she holds my tool.”

“Well, what does she have that I don’t have?”
