Ahaha! I'd been thinking it was pronounced as in French (a bit like "twah") when I should be saying it in Mike Myer's super authentic Dutch accent!
I can tell you that he does not have a Dutch accent. And the guy that played a Dutch guy was talking German. Source: I'm Dutch and also understand German.
Probably didn't cone across in the original message, but "super authentic" was meant to be ironic! (I'm pretty sure the character is meant to be Dutch in the film)
Don't worry, I'm from the UK and I can promise we don't think you sound like that!
As a Dutch guy... I'll allow it, but only if y'all admit that the Danish language is at least as silly as Dutch is (must be something about being a flat country next to the North Sea)
