"Full House" is one of the most iconic family shows ever, and particularly from the late 80s to early 90s, making a big name for many of its stars, from dad Bob Saget to the insanely famous Olsen twins Mary-Kate and Ashley; now, John Stamos' Instagram showed the actor who played Uncle Jesse in front of the house, and nobody realized it!

Although the interior scenes of "Full House" were filmed entirely in the Warner Bros. studio in Burbank, California (in the same lot as "Friends"), the exterior came from a San Francisco home that has become famous ever since, though John Stamos' Instagram post proves that not for everyone.

According to website USA Today, the "Glee" actor was walking by the house, now a touristic attraction for being the outside of the show's home, when a few fans of the show looked at it while incredibly bewildered by it - so much that they failed to see they had one of the stars right next to them, something that John Stamos' Instagram was quick to point out!

As CBS News reports, the John Stamos Instagram picture shows the 51 year-old actor in all black attire, from pants to sunglasses and a black hat, as he passed by the famous home, going completely incognito - even though he looks exactly the same way he did 20 years ago!

"Boy, these youngsters have 0.0 idea what they're missing. #Fullhousehouse. #TURNAROUND," said John Stamos' Instagram, as he posted the photo of himself with four fans of the show less than 10 feet away from him, looking straight at the house without having a clue.

Of course, just afterwards the actor called up Lori Loughlin, his wife on the show, and, according to People Magazine, the actress was "howling" with laughter at seeing just how blind these fans had been.

One point for John Stamos' Instagram right there!
