When pranking your friends and family you pretty much know the personality your dealing with, but when it comes to strangers on the street... A much different story. While everyone likes to laugh, most people don't care to be pranked and be the center of attention but if done correctly, in a harmless responsible way, most will take it in stride and join in the laughter. We would ask you please not to pull this prank on the homeless or under privileged because that is not funny, its just plain cruel! Also, please don't put a Dollar in the middle of the street or in the path of a car for someone to get ran over by a motor vehicle or worse! You are responsible for the way you use the device, every one likes a good laugh, but nobody likes a jerk.
