Fans of "Full House" visiting the San Francisco row house that starred in the popular 1990s sitcom failed to notice John Stamos posing for a photo nearby.

Stamos, who returned to the house on Friday, March 6, 2015, shared the moment on Instagram. The photo shows Stamos with a black cap and sunglasses standing in front of the home, as four people walked by oblivious to 'Uncle Jesse' right behind them.
