Russian Roulette is not the same without a gun

You know the phrase 'Russian Roulette is not the same without a gun' from Lady Gaga's Pokerface? I was wondering why you needed a gun to play Russian Roulette so i did a search on Wikipedia:

Russian Roulette is a lethal game of chance in which participants place a single round in a revolver, spin the cylinder, place the muzzle against their head and pull the trigger.

Which means a couple of people each have guns with only one bullet. Then they put the gun to their head and then they each take turns to pull the trigger until someone kena the bullet and dies.

Typically a single round is placed in a six-shot revolver resulting in a 1/6 chance of the revolver discharging the round. The revolver's cylinder can either be spun again to reset the game conditions, or the trigger can be pulled again. 19th-century Russian prisoners were forced to play the game while the prison guards bet on the outcome. In another version, desperate and suicidal officers in the Russian army played the game to impress each other.

Numerous incidents have been reported regarding Russian roulette. Many are teenagers, with some players as young as 14. (WTF) In his autobiography, Malcom X says that during his burglary career he once played Russian roulette, pulling the trigger three times in a row to convince his partners in crime that he was not afraid to die.
