Henry Winkler and John Travolta posed for a photo together at Chicago Comic Con, and of course, Rach had to hear the story behind it.
"John and I met when we first started together on television," Henry says. "They tried to make a controversy that we didn't like each other, which wasn't true."
"The only connection — I've never worked with John — I was offered 'Grease,'" the "Happy Days" actor reveals. "Now I can dance 'Grease,' but I can't sing 'Grease.' So I thought, 'you know what, I just played The Fonz for 10 years, I'm going to say no."
He doesn't regret taking a hard pass on the role, though. Henry says it was "one of the great decisions of my life, because John Travolta — who really deserved it — he said yes."
