John Stamos Nearly Bares It All in Racy Photo With Glen Powell: 'Have Mercy!'

John Stamos posted a photo of himself and former co-star Glen Powell nearly baring it all—and fans were left exclaiming, "Have mercy!"

On Aug. 30, the Full House star took to Instagram with a picture that likely made his followers do a double take.

"Walking into LDW [Labor Day weekend] with @glenpowel," Stamos, 61, captioned his update.

In the photo, the General Hospital alum wore tiny shorts and sandals while carrying paper bags that made it appear like he was in the buff. Powell, 35, wore sandals while carrying a skateboard—completely hiding anything he may or may not have worn on the bottom—while sticking his tongue out at the camera.

Fans in the comments could hardly contain their strong reactions to the racy thirst trap. Many quoted Stamos' Full House character Uncle Jesse's catchphrase, with one declaring, "Have MERCY!! ????."

A second echoed, "'Have mercy!' ??."

"You can see John wearing tiny shorts but is Glen actually ??," a third Instagram user pointed out.

Someone else confessed, "Sliding off my chair over here…," while another implored, "Next time remove the bags and the skateboard ????."

Meanwhile, another fan wondered, "Where is this available in a high-quality resolution that can be blown up to poster print size?"

Several other Instagram users clamored for another season of Scream Queens, which Stamos and the Twisters star worked on together from 2015 to 2016.

"Scream Queens S3 please ????," one fan commented, while someone else lamented, "I miss scream queens so much ????."
