Remember those British atheist bus ads in 2008 that inspired all the American atheist bus ads? You know, the ones that read, "There's probably no God. Now stop worrying and enjoy your life." Well, the British Humanist Association is now selling the original bus ads on eBay, just in time for Valentine's Day. You—yes, you—could buy your secular sweetie a piece of atheist advertising history. The BHA press release gloats that the banners prompted 326 complaints to the Advertising Standards Authority. Not only do the proceeds go to charity (atheists give, too!), but one of the banners has entered the collection of the Museum of London.
