When Jon Stewart left the Daily Show, he spoke briefly on the detecting and reporting of bullshit. He left some sage words of advice: if you smell something, say something. I thought that there ought to be some stickers or graphics or something to help further this idea.
I don't want to profit from something that I didn't originally say, so I made these stickers available for free, for anyone who wants them. Download them all as a ZIP file. If you don't want to do the legwork, I've put them all up on Redbubble so for a fee you can have some stickers made and delivered to your door.
