What do you mean Kai doesnt speak Dutch?
He speaks Spanish, Dutch, Latin, Mandarin, Japanese, and 3 southern Tibetan dialects.
He did this part time whilst getting his masters in Nuclear Physics and Theology. Now you know why he stripped and abused grapefruits on camera. To support his studies of course!
When you next see Kai on the treadmill, ask him what he's listening to on the iPOD. Most likely "chicken soup for the soul" in Latin, or one of Freud's publications in Japanese.
