I've seen other references to unusual museums on the net too, like the Coca-Cola museum (and obviously the Pepsi museum). Police museums, like the one in New Jersey featuring the actual electric chair in which the murderer of Lindburgh's baby got fried, and other ones like that. In Montreal, we have the "Just for Laughs" museum dedicated to humor (Just for laughs is first and foremost one of Montreal's many summer festivals, but a museum got created along the way) More on this at:
