Dutch prostitute twins... in their old age.

It's a new documentary movie:

"You did the work, you've been a whore," [says Louise]. "You'll never get rid of that name. They'll always call you names, so be one."...

"This is the story we wanted to tell," directors Gabrielle Provaas and Rob Schroder said in a statement. "Louise and Martine are real old-fashioned Amsterdam hookers: liberated, cheerful and not scared of anybody."

Is that their real name: Fokkens?
