I've commented on weird rental services before, but this is easily the weirdest yet. It's Rent a Dildo. It's like Netflix for sex toys. Not something many people would want to use second-hand. The site is very well designed and professional looking (though the topic itself makes it not safe for work). However when you try to sign up you read that "Though we are not yet signing up paying customers, we are testing the service with a limited number of beta users." This is code for "This is a hoax". (Thanks to Iain for the link)
While I'm on the subject of sex hoaxes, also check out Abstinence Only, a site that "offers abstinence-only education based on the strictest most literal interpretations of the Bible" (it's also NSFW). Turns out you can do quite a lot while remaining 'abstinent'.
