True, true, but I can't eat my lithium-ion battery when I'm starving, can't make a jacket out of the skin, or condoms out of the intestines when I have to sell my body...

And I believe I've seen a western with a horse (or carriage) strapped with glycerine heading to blow up something?

At least my car doesn't poop on the floor

Ah! Yes, but just like a car you don't take a horse indoors :p
