A Russian man got a nasty surprise when he returned home after a drunken night out - his wife found a knife in his back.
A friend of Yuri Laylin had thrust the blade into the 53-year-old after playing a variation of Russian roulette.
The game involved the players drinking vodka and dancing round a blindfolded man carrying a knife.
Mr Laylin said he did not feel any pain until he went home.
He said: "We had a few vodkas and I remember playing some silly games and someone had a large knife.
"I came home, went to sleep as usual and woke up when my wife started screaming.
"Only then did I realise what had happened."
Doctors said the knife went four inches into his back but missed his vital organs.
"The alcohol he drank must have acted as an anaesthetic, otherwise he would have been in great pain," one of the doctors said.
His alleged attacker reported the crime to the police himself.
