englishman, pretty young blonde girl, ugly old woman and....

4 people in the carriage of a train - an Englishman, a pretty young
blonde girl, an ugly old woman and a Frenchman.

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 Frenchman is rubbing his face, and there's a huge red mark on his cheek.

The old lady thinks "I bet that Frenchman fondled the blonde in the dark and she slapped him"

The pretty young blonde thinks "I bet the Frenchman tried to fondle me in
the dark, got the old lady by mistake, and she hit him"

The Frenchman thinks "I bet that Englishman fondled the blonde in the
dark, but the blonde thought it was me and hit me"

The Englishman thinks "I hope there's another tunnel coming up soon so
I can slap that French idiot again"

Hahahahahaha love it!

Très Bien
