The existential sadness of all of human experience can be summed up in signs like this, in that society has to put up signs in the first place in order to remind some people not to be assholes.

Love the one comment though:

I was a zamboni guy for ten years. I've seen it all. If your goal in life is to meet as many deluded jackasses as possible a hockey arena is the best place to go.
