Pornhub is nothing if not savvy with its marketing, as seen in previous stunts like crowdsourcing a safe-for-work ad campaign and going big with a (short-lived) Times Square billboard.

Who knows if it will ever be made—they say it's in beta testing, which they spell "beata testing." And they are collecting email addresses from people who might want to own it eventually. (I'm sure those addresses will be used for no other reasons.)

Here's the promo, which has well over 2 million YouTube views already:
