Most of the "insane" laws are really authors taking a general statute and conceiving of a highly-specific case that could fall under it, then presenting the law as if it covers only that highly specific case.
For example, many cities have laws about whether or not you can tie up a pet temporarily -- say, hook your dog's leash to a lamp post while you pop into your bank for a moment. But generally they're written broadly rather than specifying only a few types of "pet" animals, so then you get "ha ha this crazy law says you can't tie up a giraffe outside a bank!"
