An elderly man decided he wanted to make his younger wife pregnant, so he visited the doctor for a sperm count. The doctor handed him a specimen cup and instructed him to bring it back filled the next day.
The following day, the man returned with the cup completely empty, the lid still on. The doctor asked, “What happened?”
The elderly man sighed and explained, “Well, I tried with my right hand—nothing. Then I tried with my left hand—still nothing. My wife tried with her right hand, her left hand, and even her mouth—nothing. Then her friend gave it a go with both hands and her mouth—still nothing!”
Shocked, the doctor interrupted, “Wait… your wife’s friend tried too?”
The man nodded and said, “Yeah, but no matter what we tried, we just couldn’t get the lid off the specimen cup.”
