News John Stamos's Video of Mary-Kate and Ashley Olsen Is the Throwback We Needed By Alexandra Whittaker Updated on September 25, 2017 @ 04:45PM Pin Share Tweet Email Mary-Kate and Ashley Olsen might be opposed to returning to the Full House franchise through the show's spinoff Fuller House, but they're still making appearances, even if it's only on Uncle Jesse's Instagram. John Stamos posted the sweetest video of the twins palling around with him when the cameras were off, and the nostalgia is real. In the video, which was taken in 1989, Stamos is behind the camera instead of in front of it. He helps the two youngsters learn the difference between his on-screen name Jesse and off-screen John (because let's be real, that had to be a little confusing for the kiddos). Steve Schapiro/Corbis via Getty "John," one twin correctly guesses before Stamos mirrors her. In the meantime, her sister is behind Stamos shouting "Jesse, Jesse!" to get his attention—and our hearts grew three sizes. Once Stamos pans the camera over to her, she promptly sticks her tongue out, and it just might be the cutest moment ever. John Stamos Will Soon Star as Your Favorite Children’s Book Character Even though the Olsen twins have declined repeated invites to appear on the Full House spinoff, the rest of the gang has reunited for a third season, which premiered Friday on Netflix. Friday was also (appropriately) the 30th anniversary of the show's initial pilot. Have they come a long way or what!
