Several Strokes of Genius Mystery Cache

I was originally going to name this cache "This is the Nonsense that happens when I'm bored at work" but I figured I would like to keep my job awhile longer (I'm sure it was on my lunch hour anyway). Since I don't seem to have many strokes of genius myself, I thought I'd share some of my favorites from others.

While I did my best to do some screening, some of this content and other content you come across in the process of solving may not be appropriate for all audiences.  Please proceed with caution.

The cache is not at the posted coordinates.  It can be found at N42 4?.??? W86 0?.???   Good luck.
