Henry Winkler Makes 'The Late Late Show' Audience Laugh With Accidental Innuendo (VIDEO)

To viewers of a certain age, Henry Winkler will always be The Fonz from "Happy Days," but he's garnered whole new legions of fans -- including Queen Elizabeth II -- with his "Hank Zipzer" books.

Winkler was on "The Late Late Show" (Weeknights, 12:30 a.m. EST on CBS) to promote his new book, "Ghost Buddy," and he adopted his Fonzie voice as he was describing the plot to Craig Ferguson.

When Ferguson moved his copy of the book to one side, he explained that he did it to avoid getting spit on it. He and Winkler revealed that they both have a tendency to spit when they talk, which led Winkler to accidentally enter the realm of innuendo.

Winkler said that in order to avoid any embarrassing nasal discharges in public, "I blow before every conversation."

All Fergsuon and the audience could do was laugh helplessly.
