Full House actor John Stamos made a return trip to the Tanner residence recently, though with such little fanfare that visitors didn't even realize that Uncle Jesse was right behind them.

Stamos posted the photo on Instagram, showing him low-key in all black and sunglasses with a camera around his neck in front of the Broderick Street house in Lower Pac Heights. Maybe he was location scouting for the possible Full House reboot he might be in? Either way, those four visitors had "0.0 idea," as Stamos wrote in the photo caption, that they were in the presence of a former Beach Boy.

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