Apple may be known for its advertising prowess, but this little marketing coup is going to go down as one of the most hilarious ad placements in recent history. doubleTwist, the company co-founded by renowned software reverse engineer DVD Jon, has managed to place a banner for its product directly next to the main entrance to Apple’s flagship San Francisco store.

The ad invites passersby to try “The Cure for iPhone Envy”, which they can use to access their “iTunes Library on any device. In Seconds”. It’s clearly a message that Apple doesn’t want anything to do with. We’re hearing that Apple employees are currently scratching their heads as to how this appeared. So how did this wind up only a few feet from the store’s entrance, and directly beneath a giant Apple logo?
