I don't feed my pets heavy metals, so they must be transmuting their
organic food into heavy metals. Think of that! the ancient alchemists
must have been looking in the wrong place if they failed to create
valuable metals from dross. (PS: I'm an omnivore, so I should check my
output also).

On the other hand, maybe they're chewing on my car when I'm not looking.
