Did you know that pigs seek out and eat human feces? Me neither!
I would provide a link, but I couldn't find anything truly definitive on the Internet. I might have eventually, but I decided to abandon my search when some coworkers were looking at this lunacy on my computer and I realized the phrase "pigs eat 'human waste'" was still up in the Google taskbar.
If you know of any credible literature on the subject, please feel free to send it along.
