Bismuth Bender and Bixbite Fry

Part one of four, as requested by

I can see when the two first meet in episode one, Fry wakes up after being bubbled for a thousand years and when meeting Bender wonders what kind of gem he is. The conversation going a little bit like this:

Fry: What kind of gem are you?

Bender: Bismuth, what are you?

Fry: Bixbite. Hey, isn't Bismuth a metal? And you look like a rainbow clown threw up on you.

Bender: Bismuth can be a crystal. At least I have more colour than you, you monochrome stone.
