An Englishman, a Frenchman and a Russian are on a train

Door opens and a beautiful young woman sits into their compartment.

After a bit, while crossing her legs, the woman accidentally farts. She goes red to the tip of her hair so the Englishman gets up and says:

"My apologies, madam, gentlemen, my lunch disagrees with me"

After a while, the woman accidentally farts again. The Frenchman shoots up like a rocket and says:

"Gentlemen, please excuse me, my lunch disagrees with me".

Then the russian gets up and says:

"I'm going out for a fag, if that bitch shits herself - it was me".
