So it seems stupidity is infectious. Perhaps an indication that people have trouble thinking for themselves. Wasn't there a story once about the blind leading the blind into a ditch?

Try stopping in the middle of a crowded street and just look up, it wont be long before others do it too.

Doesn't this pattern of vertebrates' decision-making prove the truth of Mr George Walker B.'s insight-mighty saying "Human being and fish can coexist peacefully" (Saginaw, Mich., Sept. 29, 2000)?
I can't let my friend's koi decide the matter, because he (the koi) is single.

I thought it was funny that they used robot fish. I thought a difference may be, if people saw two robots walking across the road, first most of them would run and hide, and in the process pull out their phones and try and get pictures and videos. The next day, there'd be a few thousand robot videos on youtube.
Perhaps the fish were just curious. Curiosity can have some ironic twists. Fish can 'feel' minute electric currents with their lateral line. I just thought maybe one didn't have enough charge, and when there were two they arced. One robot may have been an accident, but two seemed really fishy. Of course people are always following red herrings.
