A doctor is talking to an alcoholic.
D: If you keep drinking like this, you will die in five years.
Don’t drink more than five cups a day.
The man was convinced and returned home.
After two weeks, however, the doctor found him blind drunk and lying on the street.
D: You are my patient, right?
I told you to drink only five cups a day.
A: Yes, doctor. I followed your advice.
I went to three other doctors for a second opinion after that and every doctor told me
to drink five cups a day.
So it made 20 in total.
