People are shocked, shocked, to find another big yoga instructor likes to get his freak on with his students. This one sounds pretty sketchy to me. I define abuse as something that continues to happen after someone says, "no," or is physically or chemically rendered incapable of saying it. That's not what this sounds like. I'm not completely sure it's even an abuse of power, since "yes" means "yes," at least to me. Sounds more like a bunch of high-minded hipsters got a nasty shock when their spiritual leader turned out to be human just like everyone else.
What's that? Oh, yeah, we tried yoga a few times. Ellen's just fine at it, but my efforts result in a lot of whooping and crashing into things, along with comments like, "really? That's as far as you can stretch?" and "you look like you're trying to crap out a bowling ball." Bicycles, man, bicycles!
