HANDS DOWN...

An elderly man 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. He took it and left the clinic.

The next day, the elderly man came back, looking worried. The specimen cup was empty and the lid was still on it.
"What's the problem?" asked the doctor.
"Well, I tried with my right hand... nothing," the man answered.
"I tried with my left hand... nothing. My wife tried with her right hand... nothing. Her left hand... nothing. Her mouth... nothing. Then my wife's friend tried. Right hand, left hand, mouth... still nothing."
"Wait a minute," the doctor said.
"You mean... your wife's friend too?!"
"Yeah," answered the man, " and we still couldn't get the lid off of the specimen cup."
