The TV in my living room is operated by a remote control that came with the cable box. As long as I leave the TV set on channel 3, I can use the remote to change channels, adjust the volume, and turn off all the components from the couch.
For some strange reason, my dog decided to chew on the remote this morning after I left for work. When I came home, the chewed remote was laying in the middle of the floor. Arrrrg!
