Sometimes, you get an irritation that just begs to be relieved with a nice scratch. And maybe it's located in a hard-to-reach space, so you need to find something to sidle up against and use as a scratching post.

And before you know it, you've satisfied that itch, but you've sent some poor mine train cruising backwards in a course completely opposite to what they were originally headed. Well, I guess in that case, it's just a bear-y unfortunate turn of events, isn't it? A grizzly relieves an itch inside Big Grizzly Moutnain Runaway Mine Cars.
