The main reason for sending Producer Joe out on the streets to interact with people is so we can hear and experience the awkwardness that he usually encounters. A few years back, we had the idea to send him out with a bluetooth piece in his ear, talk directly to people and when they responded, follow it up with "I'm not talking to you. I'm on a bluetooth!".

Yesterday, we came across a video of something very similar called cell phone crashing. Basically, you find someone talking on a cell phone and stand right next to them on your cell phone, responding to everything they say. This will most likely be a Joe stunt sometime in the near future.
