Dr. Kurt Schwenk
It was a pretty incredible gift to be able to work with Kurt on this episode. His work spans decades and it took multiple tries to understand it in a way that could be put together in a narrative. I am very grateful for all of his time, warmth and generosity. I had to leave many, many wonderful pieces of research and factoids out due to time constraints but I would urge any of you that are interested to dive deeper into his work.
His colleagues Dr. William G. Ryerson, Ms. Amanda E. Hewes and
Ms. Sara Horwitz contributed a great deal to some of the research that I mentioned.
Dr. Margaret Rubega ( deserves thanks for introducing me to Kurt in the first place.

So reptiles use their demon tongues to lick the ground, then snort up whatever they find through their mouth nostrils. Because snakes apparently have nostrils on the roof of their mouths.

Hey Frank. As one genius to another, I propose a market that will over double your cash market. I have always loved your humor and attention to detail. I know that this is only a love of leisure that you don't really need. Thank you for keeping on. You have the capacity to educate young minds with your great humor! If you are willing to make videos for children , you have the chance to grow greater than Bill Ney the "science guy". I would love to see you share your knowledge and humor with my son. He's 10. Please create this page. You might even get picked up by PBS if you do it right

This was very informative. Seriously. I'm gonna need to watch this video again...and then get super slow-mo footage of my hognose snake's tongue. That perv, Dr. Schwenk, might pay me for it. J/K ;) I'm super impressed he figured out all this stuff.
