Interesting analogy Bradley :) Let me also add, that when hashing, you
generally don't modify the frog. You build the hash by using the frog,
but the frog itself remains a frog :) Sort of like a checksum (and in
fact, hashes are usually used just for that purpose).

I am curious, have you ever actually put a frog into a blender? :)
