- "Help, I need tungsten to live! Tuuungsten!"
- ―Allan Wrench
Alan Wrench is a metallic-based lifeform who was found in a meteor that crash-landed on planet Earth. He currently works in a Swedish furniture store in Springfield. Virtually nothing is known about this alien's homeworld and biology, except that it has a strong biological need for tungsten.
- In real life, there are some species of bacteria that do require tungsten to live, which makes this metal the heaviest chemical element used by living organisms.
