Canadian curiosities

Now that we're safely back on the U.S. side of the border, I have to question a few of the things we saw. For instance, what does this sign mean?

Beware of person with detachable hand?
Beware of person bowling? Playing basketball?
And did I mention the sign was posted in the middle of nowhere? On a lengthy dirt road that led to the amethyst mine?

Something else I noticed: what is wrong with this picture?

Notice that the drain is at the front of the toilet?

Kind of different, eh?
