Does Bill Murray do yoga?

I'm specifically curious about Bill Murray in The Life Aquatic. Replace the orange hat with a turban, and he definitely could have been the substitute teacher at my yoga class yesterday. Maybe his Life Aquatic character was based on this man. Or it's another Borat-like film in the making, which seems probable judging by the fact that we spent an hour and a half mostly walking in circles and trying to exhale as loudly as we could. I think I'm going to just do yoga alone in my apartment until I hear that the regular teacher is back.
