The porn industry is a tricky business. All your movies are rated XXX, but you can't show full on penetration on a billboard, or can you?

Well it turns out that you can't, but that didn't stop PornHub from coming up with a genius marketing strategy.

Rather than coming up with their own idea, which is way too much work, they asked their loyal viewers to create a G-rated ad for them, and it worked beautifully.

They have limited it down to 15 finalist and are asking for you to vote on your favorite one. You can cast your votes on their Tumblr page, and check out some of the best below.
