A Doctor recently had a patient "drop" in on him for an unscheduled appointment. "What can I do for you today?" the Doctor asked.
The aged Gentleman replied, "Doctor, you must help me. Every time I make love to my wife, my eyes get all bleary, my legs go weak, I can hardly catch my breath. . . . doctor, I'm very concerned!"
The doctor, looking at his 86 year old patient, said,: "Mr. Smith, these sensations tend to happen over time, especially to a man of your advanced years, but tell me, when did you first notice these symptoms?"
The old gent's response was, "Well. . . three times last night, and twice again this morning!"
