It's been more than 20 years since "Happy Days" signed off for good, but Henry Winkler still has fans clamoring for autographs -- with Fonz pics in hand! Heyyyyy!
TMZ caught Winkler leaving an event in Los Angeles last night when a few fans stopped the star for his John Hancock. But Henry said he only had time to sign one, and then quickly had to move on.
Don't be such a Potsie!
