Richard Dreyfuss is my dad's doppelganger. My dad has been mistaken for Dreyfuss more than once and asked for his autograph. The funniest part about that, in case you didn't realize, is that there are people in the world who want Richard Dreyfuss' autograph.
Carrol O'Connor looks a lot like my dad, but isn't quite my dad. Sammy Davis Jr. once kissed them both, so I guess that makes them Eskimo Brothers. Still, not my dad.
