Barber, his wife and her lover
A barber suspected his wife of having an affair after neighbours tipped him
off that one of his customers was the culprit.
He knew the exact time the barber would leave the house for the shop and he discreetly crept into the house to meet with the barber's wife.
One day, the barber decided to set a trap for them.
As soon as he left the house, the lover sneaked into the house unaware that his liason with the Barber's wife was out in the open.
Several minutes later, the barber went back home and from the front window of the house, he was able to have a good view of the man's face. He went away and never did anything. He even arrived home later that day and said nothing to his wife.
Then one day, the same man came into the barber's shop to cut his hair. He had side burns (George Micheal style) and wanted this trimmed as well. Then the barber took his time cutting his hair and making sure every detail of his hair was profesionally done. Then he switched to the sideburns.
Our guy relaxed, checking himself in the mirror and thinking to himself what a silly
fool the Barber was. He was having an affair with his wife and he was cutting his hair. Anyway, what he didn't know wouldn't hurt him.
Meanwhile, as the barber finished trimming the left side of guy's sideburns, he turned to the right side. In no time, he had finished that as well.
Then lastly, he decided to trim the mass of hair underneath his beard when he placed the scapel on his throat and said "Sho mo pe mo mo sha" (Translation: Do you know that I know what's going on?)
