Ha Ha, That’s the Point !

The municipality of Saint-Louis-du-Ha! Ha! located in the province of Quebec in Canada, just north of Maine in the United States, is the only city whose name includes two exclamation points?
The name has its roots in the ancient French term “The haha” which meant a dead end or unanticipated obstacle which referred to Lake Témiscouata which early French explorers encountered unexpectedly.
