20 Mind-Blowing Facts You Never Knew About Futurama

11. Zoidberg Originally Had Teeth

The original joke with Zoidberg, that he knows nothing about humans, hasn't really been messed with over the years; as the series ended he was as incompetent as ever. However, that doesn't mean he's not been changed at all.

Despite intended to be an utterly unreal character (he even wears sandals), originally Zoidberg was drawn with teeth. I guess it was just assumed all characters would have then; Bender does after all. Realising it humanised him a little too much, these were removed a few episodes later in My Three Suns.

The odd thing, however, is that Decapodians do have teeth; in Why Must I Be A Crustacean In Love Edna says she was busy brushing her teeth. How inconsistent.
