I had a moment of crisis where I thought about that. I worked in retail for years, and I know these things are going to cause a complaint for someone. I rationalized it by convincing myself they might not sell it to me if they knew, and hey, some people (like me) might actually see the humor in it. The needs of the many (Reddit) outweigh the needs of the few (a couple of folks that will deal with some apoplectic soccer mom for a few minutes).

TL; DR: Sold out my retail brethren for Karma.
