Did you perhaps see any invisible dogs at Improv Everywhere's Invisible Dog Walk?
An organizer explains:
For those of you who were not there - we passed out over 2,000 "invisible dog" leashes and had everyone go for a nice Sunday walk in Brooklyn. If you were anywhere within a one mile radius of the Bergen St. stop in Cobble Hill today, you would have seen all types of folks very seriously walking their very silly dogs. The invisible dog toy was invented in the 1970s in the Brooklyn factory that served as our meeting point today.
Agent Lorna reports:
I miss my dog. My favorite was a lady explaining it to her child. She said…. "Yes hon, that is an invisible dog, a very rare breed." lol Tried to buy a treat for my invisible dog at a pet store and the guy wouldn’t let us in. He was a pooper. At the Barnes & Noble the lady guard asked me what "that" was. I said "My dog." She advised me in the kindest way that I had to leave the second floor because dogs were not allowed up there because of the café. lol
And
Another moment was in the Trader Joes. We were on line and a lady and her son were behind us. (we had 2 maltipoos, Jessica Simpson dog. Her dog was killed recently by a coyote) This boy just got so involved with the dogs. He would pet the dogs and just yell "…but I don’t feel anything!" Cool thing was watching people step around our dogs when they went up to a shelf to get something...
This is the kind of silliness that I can get behind pretty much totally. It is art. It is play. It is fun. It doesn't threaten. It doesn't invade anyone's space. It provides people with an opportunity to be playful. To be pleasantly surprised. Or to ignore it, and the world, as much as they need to.
