Playing Doctor

Morris complained to his friend Irving, that love making with his wife was becoming routine and boring.

- Get creative Morris. Break up the monotony.

- Why don't you try 'playing doctor' for an hour? That's what I do - said Irving.

- Sounds great - Morris replied.

- but how do you make it last for an hour?

- That's easy...just keep her in the waiting room for 59 minutes!
