I'm friends with Les Blank's son Harrod. And used to date a girl with gap teeth. Les was all over her trying to snatch her away. Good times:

Weird... I submitted this before you posted that, but it's on the front page.
I would like to know more anecdotes about Les.
I think he is one of the best food documentary filmmakers out there, or was. He would have surely had cooking/traveling shows had he only been at his prime these days.
