My initial thought upon seeing The Ultimate Fighter house for first time was, “Oh my dog, we have a moat.” Granted, it wasn’t a huge moat. More like a stream trickling underneath the walkway that led from the driveway to the front door, but I’ve never lived in a house with any sort of moat at all, so I was impressed. At that time, I was living in a crummy little apartment in a crummy little neighborhood in Nashua, N.H., so the house looked to me like an absolute mansion. I mean, there were marble counters in the kitchen and a mothersqueaking waterfall in our swimming pool
