John Travolta Hangs With Henry Winkler: Danny Zuko & The Fonz!

Two of the biggest stars to ever portray 1950's era bad boys finally met up and fans are going nuts.

John Travolta and Henry Winkler posed for a photo together over the weekend during Chicago Comic-Con.

Travolta shared the pic and wrote, "Been a long time since I saw Henry Winkler and we got to see each other again at Chicago comic con."

73-year old Winkler was smiling wide while the 65-year-old "Pulp Fiction" star leaned in for a solid embrace.

Travolta is out during a promotion tour as his new movie, "The Fanatic," just premiered.

Winkler, perhaps best known for his role of Fonzie on "Happy Days," has long been compared to Travolta's portrayal of Danny Zuko in "Grease."

In fact, the "Water Boy" star revealed a few years back that he turned down the role of Zuko during his "Happy Days" run, because he did not want to become typecast.

"I turned down the lead role in 'Grease.' Didn’t want to be typecast. But you’re typecast anyway. And it’s not now that I’m, like, 'Oh, I should’ve done the role.' It’s that I turned it down intellectually instead of instinctually," Winkler explained to AARP Magazine during a 2017 interview.

However, the actor also admitted it wasn't the best decision, joking, "I went home and had an orange juice. Travolta went home and bought a plane."

It's a good thing Travolta recognized his old friend, considering his recent gaffe during the MTV Video Music Awards when he almost gave away Taylor Swift's award to her drag queen counterpart.
