You're in the Peace Corps

I just want to point out that my room mate and I have spent more time than I care to admit discussing the length of a particular dog's nipples. Why is the one nipple so much longer than all of the rest? Why is this a topic we've brought up more than once? How does living the Peace Corps life bring me too this point? How do I choose between discussing the nipples on the dog or the emotions of the passing cows?
