Like Bender's devil eyes? But he really isn't the devil in the house...
Barbie can be very manipulative. She figured out a new trick yesterday when Bender was occupying her spot on the couch. She got up from her bed, ran to the front window and barked. Bender had a puzzled look on his face, he hadn't heard anything outside, but he couldn't let Barbie upstage him, so he got up and raced to the window as well.
As soon as he left his position on the couch, Barbie left her newly adopted guard post, and jumped straight into his spot on the couch.
