An 80 year old man is given a jar to provide a sреrм sample for the doctor, he turns up two days later with an empty jar.
The doctor asks ‘Why don;t you have a sреrм sample?’
The man says ‘Sorry, I tried with my right hand, and then with my left hand, and then with my wife hands, and then with my wife’s mouth, 1st with her teeth in, and then with her teeth out, then with Ethel from next door but it was all no good.
We just can’t get the jar open!
