Pop quiz, hotshot: Carissa and Billy Gaghan were nine and 12 years old. How fast do you think they would have been yanked into the penalty box if they had even subconsciously considered throwing trash at another team? What are the odds they'll be doing that when they're 19 and 16? Just offering a little food for thought.

Over in the Linz car, Nick tells Alex that the clue says to go to the Grand Canyon, and Tommy (whom I at least did not have confused with Megan) starts salivating over the idea of a Grand Canyon Detour. "Maybe ride some don-kays," Nick comments. Man, I'll tell you, this is not easy. I had finally really and truly absorbed who these two guys were. My brain was fully committed. It's like finding out that Mirna is the short one. I'm still totally disoriented.

Wally and the Tonyas, pulled over for directions, ask someone to borrow a cell phone. Wally makes a call -- probably to the park -- and asks about getting to Lipan Point. "Should I be coming in on 64 or 89?" he asks. He pauses. "Okay...89." We cut directly to Papa Paolo telling DJ to take 40 West to 64 North. "It's got to be along that 64," he says. Dun-dun-dunnnn! Brian looks dubious. "I hope so," he says. Mm.

The pinks approach the sign that says there's a vehicle fee of $20 to get into the Grand Canyon. Up ahead, as the Weavers approach the booth where you pay that fee, Rachel suggests that they tell whomever they pay that the car behind them really wants a complete history lesson. That is a very well-thought-out plan, except for the fact that it makes no fucking sense. The girls are talking about how one of them is really going to do say this. "No," Mama Weaver says, and for a moment, it appears that she's actually going to draw a line and tell her daughters that, having already thrown trash out of a car window at other people, perhaps they've done enough dickhead things for one day and should pace themselves. But what actually happens is that the girls indignantly ask why they can't do it. The response? "I will," Mama says calmly.
