Elderly Joe Vickers faced Doctor Reed and asked for a full physical examination.

The doctor looked puzzled, “Why now?”

Joe smiled, “I’m getting married.”

“That’s splendid.”

 “I’m eighty-two and she’s twenty-four,” Joe said.

The doctor looking dubious, but he conducted the examination.

Afterwards, he observed, “No real problems considering your age. Could I make one suggestion?”

“What’s that?” Joe asked.

“Having a lodger might keep your wife—er--” Doctor Reed hesitates, “--company.”

Joe agreed and left, but two months later he returned.

“Everything okay?” the doctor asked. “How’s the wife?”

“She’s pregnant.”

“Amazing. Did my suggestion of a lodger help?”

“Definitely, she’s pregnant too.”
