Okay let's go ahead and change the words to "Dude Looks Like A Lady" to "Bear Looks Like A Human".  This could also solve a couple of those bigfoot sightings/mysteries.

So I keep imaging the bear going "Bear, what bear? I'm a hoo-man! See I walk just like a hoo-man!  Oh, what's in this trash? Oh wait, hoo-man's don't look in the trash, dee-dee-dee."

So check out the video and see if it doesn't change your perspective on bears and animals a bit. Once you see one walk upright it seems like they have more personality.
