The S5 are off and running, completely missing the fact that they are standing on the first letter, despite Peachy's initial announcement: "You are looking for eight letters total. You're standing on the first one." As they run off in chaos, Peachy chases after them yelling, "You're standing on the first one, guys! You're standing on the first one!" Finally, Clay figures out what Peachy is talking about and heads back to the starting line, and the others slowly follow, except Brian, who is still confused. He crosses paths with Clay and asks, "Where we goin'?" and Peachy answers, "You're standing on your first one!" So Brian figures it out while the others have all moved onto the trough.
At this point, Peachy reminds the S5 that they're "looking for an underscore." He adds, "Underscore means English letter," which totally disappointed me because I thought he was going to say, "'Underscore' means 'underlined.'" Jan has the most difficulty with this leg of the challenge, and as the others move on, we see a shot of her sorting through the tiles, throwing the Thai symbols over both shoulders after she looks at them. It's a waste of time, but it's hysterical. Peachy coaches Jan not to give up with the claim that she's "still alive," but then immediately rubs it in: "Everybody's got four except Jan." By this point, Clay is in the lead with five letters, followed closely by Brian. At the rope pull, Clay gets lucky on the first one, while Brian has to try again. When Brian reaches the trunk, Peachy calls out that there a "nice little surprise in there," which looks like raw fish. In any case, the blow-by-blow of the first part of the challenge matters very little, as it all comes down to the unscrambling part. Peachy reminds them that they're looking for "two words when put together are an activity."
