I don't think anyone says it's impossible - just extremely counter-intuitive.

  At some point when I thought about it, it appeared to be counter-logic, not just counter-intuitive. I extended the experiment by placing myself in the closed room with the cat. Luckily for the cat, the poison stays in the jar and I observe a very live cat, while the people outside the room are considering whether there's really a superposition of me with a live cat and me with a dead cat... After researching it a bit more, I learned Eugene Wigner had already considered something similar: http://en.wikipedia.org/wiki/Wigner%27s_friend http://en.wikipedia.org/wiki/Wigner%27s_friend
