What is the MOST METAL VEGETABLE?

They grow in the underground, they're ugly, dirty, and if you stick electrodes in them, you can run a watch.

Definately the Carrat, be it the nice phallic shape that we all know and love, or the distorted twisting evilness of a retarded MUTANT carrat.

Mom showed me a carrot with too long bits, and a tiny short tiny bit in the middle. it was the most "Legs and penis"-like carrot I'd ever seen. I ate it.
