Listening To See If Everything Has The Same Heartbeat

In this performance the artist wandered the streets of downtown Olympia with a stethoscope. He would occasionally stop to listen to a window, a building, or a bench and then his own heart. After pressing his stethoscope to a rock, his sister and a rack of clothes he was asked to explain his actions. He answered, "I'm listening to see if everything has the same heartbeat, so I can learn." The artist then placed the stethescope to his sister's head and declared, "Hmmm....it sounds like a lightening storm!"

Interesting, but we still aren't getting a pet

I'm thinking of an animal with a long tail and lots of fur.
-hmmm.... how about another clue?
It starts with a "g".
- a goat?
No, it says- ooooooooooooh!
-uhhh....
A ghost dog!
