A man commits a crime and has to stay in prison for five years.
Without having too many illusions, the man recommends to his wife:
“Dear, please be honest. In these five years, put a grain of rice in this drawer every time you cheat on me”.
Five years pass and the man returns home. He immediately rushes to check the drawer and finds only three beans.
He then says to his wife: “Did you only cheat on me 3 times?
You’re a saint!” and his wife: “But what about all the risottos I sent you?”.
