Go GREEN!...Throw out that old ELECTRICKERY burning monster and go for a bio-gas model...
First, rip out all the bits that look like wires/switches/elements etc, then when left with the empty case, attach a few 10mm diameter hoses at various places around the sides.
Stick other end of hose in your ar....erm...wherever, and also get a few friends around and connect them to the oven in the same way.
Then you and friends consume copious amounts of baked beans and Brussels sprouts. When gas pressure in oven is high enough, ignite and run!!!!
