People eat bull testicles here too...there is actually a pretty big "Calf fry" that goes on here every year, and that's what it is. That's what rocky mountian oysters are as well...animal testicles.
I didn't know the snake in the liquor was something that was done in other cultures, you learn something every day!! I do think it's pretty low of the guy to sell the stuff as a healing elixer when he knows that it's not, or at least it's not in the sence that he was trying to sell it. Just b/c the people he was selling to believed thought it was, doesn't make it something special.
