Here's a good example of the effectiveness of using humor in your protests. When I arrived at this street corner there was one young woman there holding an Obama sign, and she was being showered with a lot of really nasty dehumanizing insults. Everyone else on that corner were Tea Partiers (and knowing Florida's now-infamous law it's possible that some of them were carrying concealed weapons).
So I walked into the fray with Pete the Pissed-Off Polar Bear, and, as you can see, they were basically good-natured toward me. You can tell in the video that I'm not looking them in the eye, I'm forcing them to deal with a puppet! And they can't help but laugh at the absurdity of their predicament. It's hard to argue with a puppet!
