4 people in the carriage of a train – a Jew, a pretty young blond, an ugly old woman and a Muslim

It all goes dark when the train goes through a tunnel.
In the dark there’s the sound of an almighty slap, and when the train emerges from the tunnel the Muslim is rubbing his face, and there’s a huge red mark on his cheek.
The old lady thinks, “I bet that Muslim fondled the blond in the dark and she slapped him.”
The pretty young blond thinks, ”I bet the Muslim tried to fondle me in the dark, got the old lady by mistake, and she hit him."
The Muslim thinks, “I bet that dirty Jew fondled the blond in the dark, but the blond thought it was me and hit me.”
The Jew thinks, “I hope there’s another tunnel coming up soon so I can slap that Muslim moron again."
