From a product description for wasabi at Penzey's Spices:
When you've been going to the candy store all your life eating turtles, luscious chocolate covered caramel and pecan creations, and then you get told no, real turtles are at the pet store - so you go there and find out they are crunchy amphibians, even though they truly are the "real" turtle, you'll probably, in the long run, end up back at the candy store.
Seriously. I didn't make it up. It's Jped's fault, he sent it to me.
