There was an elderly man who wanted to make his younger wife pregnant. So, he went to the doctor to have a sperm count done. The doctor told him to take a specimen cup home, fill it, and bring it back the next day. The elderly man came back the next day and the specimen cup was empty and the lid was on it. Doctor: What was the problem? Doctor: Wait a minute. You mean your wife's friend too?! Elderly man: Yeah, and we still couldn't get the lid off of the damn thing!
