This may have been posted before but I watched it like 50 times and couldn't stop laughing: <object width="425" height="355"><param name="movie" value="http://www.youtube.com/v/FzRH3iTQPrk&rel=1"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/v/FzRH3iTQPrk&rel=1" type="application/x-shockwave-flash" wmode="transparent" width="425" height="355"></embed></object>
After watching it a couple of times, I don't think the big bear sneezed. The little pup bear screamed at something and big bear just reacted.
Aww, poor panda locked in a cage because its natural habitat is drying up. Wait, don't panda's eat people? No that's polar bears.
No, the big bear was dropping crumbs all over the little bear causing it to sneeze, then the big bear reacted to that. In summary, the big bear caused itself to react like that.
