Soap viewers see photos of stars every day on social media, but General Hospital alum John Stamos (ex-Blackie) decided it was about time fans saw a moon, too. And... let's just say it had nothing to do with the eclipse.
The Full House star has the Internet abuzz with a revealing social media photo of him in his birthday suit -- which is quite appropriate because he's actually celebrating his 54th birthday.
"#54 and clean," Stamos captioned the butt pic. "Thanks for the birthday wishes!"
Response to the provocative photo has been all over the map, but most would agree it deserves a big, fat, whopping "Have mercy!"
