I used to believe that Henry Winkler (who played The Fonz on that old show Happy Days), was called Henry WRINKLER. I thought this was an incredibly odd last name.
I actually debated this one with my mom, when I told her that Henry "Wrinkler" was playing in that Adam Sandler movie, "Waterboy"- it took her forever to convince me otherwise...
