...Ok so it's an assumption but, surely he's only had time for one Norwegian skiing trip this year....
"I became hypothermic recently when I went skiing in Norway with some friends. I don't remember the experience too well, but apparently I had become delusional and tried walking down a mountain in my sneakers and jeans at minus four degrees Fahrenheit. Pretty stupid."
Clearly, he's recovered okay from this ordeal ... but perhaps they should record somewhere warmer next time.. ;-)
