Dog

One dog barks at something. The rest bark at him.

 Lily barks. She barks at people who walk by the house. She barks when we get a package delivered. She barks if there is a chair in the yard someplace where it doesn't belong. She barks if Tippy tells her something is happening and they should bark at it.

One night she was barking. I told Leslie our neighbors had come home and walked into their house. 

Leslie: Well, that solves the mystery of the barking dog.

Me: There are a lot of episodes in that series.
