And you call yourselves "Full House" fans. A couple of devotees of the sitcom that gave the Olsen twins their start were paying their respects at the San Francisco home used in exterior shots for the show — and totally missed a special treat. Standing right behind them was "Full House" star John Stamos, who apparently likes to make pilgrimages to the site as well. He even documented the oblivious fans for the Instagram audience to enjoy.

Boy, these youngsters have 0.0 idea what they're missing. #Fullhousehouse. #TURNAROUND.
