We had an African Grey parrot for a while; those are awesome smart pets
My cousin wanted to be a pirate for Halloween once. He decided it would be neat to let our bird ride on his shoulder as he walked house to house. He walked outside, the bird flew away. Very, very smart bird.
I've seen a different video of what I believe is the same parrot (the guy's voice was the same in the other vid). And he's swearing like crazy. It's actually really funny. lol
