I participated in Improv Everywhere's most recent mission.
My friend Lauren Reeves invited me to come to the "top secret" shoot. All I knew about this particular improv group is that they are known for going pants-less on the subway. So I was very relieved when people started walking out of the "secret" building with their invisible dogs and no missing clothes.
Watch one of their most famous stunts that took place in Grand Central Station. Its pretty awesome.




My favorite moments of the day were all the children who were so joyfully excited to be petting my invisible dog. One little girl who was participating insisted that she was walking an invisible Iguana. For me, well, I decided to walk the spirit of my childhood dog, Sparky.
