Face slap in a train carriage.

A Glaswegian, an Australian, a Nun and a attractive woman sit on a train. The lights in their car are defective consequently in every tunnel it gets really dark.

The train drives through a tunnel, it gets dark and suddenly you hear a slap and someone cries out in pain. When it gets bright again its obvious that the Austrian was slapped in the face.

• The nun thinks
  The Australian tried to grope the young woman, so she slapped him.
• The young woman thinks
  He tried to grope me but messed up and touched the nun so she slapped him.
• The Australian thinks
  That Scottish guy tried to grope the woman and she tried to slap him, missed and slapped me.
• The Glaswegian thinks
  In the next tunnel I’ll slap him again.
