Have mercy! Uncle Jesse has returned!
John Stamos posted a photo from the set of Fuller House, the Netflix reboot he's not only acting in but producing as well.

The Instagram snap proved that even though he's also starring in a sitcom titled Grandfathered, Stamos has barely aged a day since Full House premiered in 1987. (Yes, that's almost 30 years ago. No, we don't know how that's possible either.)
"And we're back!" he wrote. "Same sideburns -- different decade."
Even more nostalgia-inducing was the tweet Stamos sent a few hours later, writing he was "home again after 25 years."
