What was the name of the show? I don't watch TV much (embarassingly, I did not even know how to turn it on or off when we had company over), and there have apparently been short pieces in several different shows on Nat Geo and Discover Channel. I can't keep track and have not seen most of them. Recently, there was a couple of minutes in a show called Weather Rampage, of all things (don't ask me why carp are in a Weather Rampage show, and don't ask me what a fish biologist is doing in the US Geological Survey, either - I could tell you but I'd have to kill you [with boredom]).
