Sitting together on a train traveling through the Canadian Rockies were a fellow from Western Canada, a fellow from Quebec, a little old lady and a young blonde girl with large breasts. 

 

The train goes into a dark tunnel and a few seconds later, there is the sound of a loud slap.  When the train emerges from the tunnel, the fellow from Quebec has a bright red hand print on his cheek.  No one speaks.

The little old lady thinks:  The fellow from Quebec must have groped the blonde in the dark and she slapped his cheek.

The blonde girl thinks:  That fellow from Quebec must have tried to grope me in the dark, but missed and fondled the old lady and she slapped his cheek.

The fellow from Quebec thinks:  That fellow from Western Canada must have groped the blonde in the dark.  She tried to slap him but missed and got me instead.

The fellow from Western Canada thinks:  I can't wait for another tunnel so I can smack that asshole from Quebec again.
