3 idiots rob a jewelry store

The doctor tells the 90 year old man that he needs a semen sample. "Bring back the specimen tomorrow." The next day the old man comes back with the jar in hand. It's as clean and empty as it was the previous day. "Did you have a little trouble?" asked the doctor. A pause, then he says, "When I got home I tried, you know? First, with the right hand. Next, with the left hand. Nothing. That I asked my wife for some help. She tried too. With her left hand, with the right hand, with her mouth, she even put it under her armpit. Nothing. Now we got us a friend, down the street. She helps us with things now and again from time to time, seeing as how we're getting on in age, and she's trying with her left, with her right.." "Hold on," the doctor says, "you asked your neighbor for help?" "Yeah, but none of us could get that jar open."
