Jerry: (doing stand-up) I had a parakeet when I was a kid, that was the only pet that I really enjoyed. We used to let him out of his cage, and he would fly around and my mother had built, one entire wall of our living room was mirrored. She felt this gives you a feeling of space. Have you ever heard this interior design principle that a mirror makes it seem like you have an entire other room? What kind of a jerk walks up to a mirror and goes, "Hey look, there's a whole other room in there. There's a guy in there looks just like me." But the parakeet will fall for this, you'll let him out of his cage, he flies around the room, BANG! With his little head, he would just go 'click' Ohh! And I'd always think, even if he thinks the mirror is another room, why doesn't he at least try to avoid hitting the other parakeet?
