First up, I offer you a link to a story about an unusual way to make beer, using yeast harvested from the brewer's own vagina. You down wit OPB, (Original Pussy Beer)?
Next up, From a friend that just had to google for more on the subject, we have a link about a well-intentioned but misguided gentleman and his process for making yogurt.
Things that make you go ewwww.
