At the police station, a citizen appears and says he wants to confess... The police chief asks: - What happened? And the man: - Doctor I killed my mother-in-law! - Well my son, you committed this crime but you should be very upset - said the chief - don't mind, go home and rest. It's alright.... - But doctor I buried the old woman! - Oh my son saw what a good soul you are? He buried his mother-in-law. So you've already avoided all that bureaucracy... - Doctor!!! But when I was burying her she screamed that she was still alive! - It's my son and you don't know that every mother-in-law is a liar?
