Speaking of Kelly and Jon, here they come to the Roadblock clue. Kelly declines this one, and Jon agrees to do it, and they share a little smooch. As he prepares to go, he explains that he doesn't want to get his underwear wet, so he's thinking that he'll just do the whole thing naked. "If you want to go naked, go naked. I dare you," she says. Hee. Jon takes everything off and goes naked. "That's a full moon, baby!" Kelly calls as he runs down to the water. "Be very careful," she says. "Don't damage the merchandise!" Well, it is hers, after all, for good or for ill. Even if you're not happy with your new sofa, you still try not to spill stuff on it. Jon swims. Once he retrieves the rock and returns to the beach, Kelly chuckles, "Do you want to put your panties back on?" He does not. He puts hammer to chisel in very close proximity to the friendly family, as David would say. And as her naked boyfriend hammers away, Kelly comments, "It's like Adam building his first house," which is one of the only episode title quotes this season that has been genuinely witty.
In the Chipster car, Reichen marvels at his own mad map-reading skillz, while Chip continues his iconic behavior of grimacing and driving.
Jon finally splits the rock, and Kelly reads the clue as he gets himself dressed. They return to their car and head for the national park.
The Chipsters turn off at Chain of Craters Road, and they run to the aforementioned lava field. They make their way to the clue box and pull the clue. It tells them to get themselves to the anchor of the U.S.S. Arizona, in Phoenix, Arizona. I'm sorry, Phoenix? Nothing against Phoenix, but...Phoenix? As the final city? I guess Omaha was closed. Anyway, Phil explains that when they get to Phoenix, they'll have to search for the anchor monument. The Chipsters run back to their car in their usual Chipster fashion. They take off, as Reichen explains that there were two possible airports -- Kona and Hilo. Reichen recommends Hilo, because it's closer.
