Mushaboom, Ong bak and brown cheese

Right now I'm loving 'Mushaboom' a song by Feist, and 'Ong bak' the film, the guy does all the stunts himself, whoah! Seriously impressed.
On other topics, I still have my finnish friend here, we're doing just fine, eating way too much candy and introduced him to the Norwegian Brown cheese. He thought it was weird but as everyone fell for the caramel-like, round flavour. The cheese is heavy, with a sweet and rich scent and taste. The slices must be cut thick and put on freshly baked bread. mmmmmhmm, brooown cheeeeeese.

This basket full of brown cheese, and this hot Norwegian chick can be yours if you answer the following riddle:
What does these Finnish sports have in common?
- motorbike riding
- downhill-skiing
- Icehockey

Let me tempt you with a fresh image of the most exotic culinary experience, Brown cheese:
