Ambiguous Gender: AD & Fuzzie, Asia Season 3. At first glance, they look like two male friends competing. But they are actually females.
Anti-Climax: The finale of Asia's fourth season was one. One of the teams was on a flight that arrived hours after the other two teams, and half-way through the episode the team that was in second quit the Roadblock and took a 4-hour penalty.
The Cameo: Paula, a contestant from Asia Season 2 was the greeter of the first leg of Amazing Race Asia 3.
Geoff from Asia Season 3 did have an appearance in Amazing Race Asia 2. He is known as "Sam" even though Marc called him Geoff. Still not convinced? Check out this vid: http://www.youtube.com/watch?v=hAwzqN4BAG4& around 8:29.
Crazy Consumption: Michelle from Asia Season 4, she started to act very loony and twitchy as she consumes the live witchetty grub.
Dark Horse Victory: Zabrina & Joe Jer, from the first season of the Asian version of the race, were considered underdogs, not athletic, never won a leg and were lucky to be saved by a non-elimination leg. They then excelled in the final leg and became both the first female team to win the race, and the first team to win the race without winning a previous leg, even by Fast Forward.
Determinator: Sharon, on the "dig through sand until you find a mini surfboard" Roadblock in Asia Season 1, Episode 3. She kept on digging long after the sun had set and all the other teams had left or given up, telling her teammate Melody that even if they were definitely in last place, she just wanted to finish this task, no matter how long it took. Unlike with Lena from US Season 6, this paid off for her in the end as she finally found the surfboard well into the night and overnight bunching enabled her and Melody to catch up to the other teams and pass those who had given up on the task and taken the 4-hour penalty. (They finished 3rd for that leg, out of 9.) Their efforts are best summed up in this exchange:
Melody: "If we leave now, we give up now, we're-we're the last team."
Sharon: "If I-you know if we got eliminated today, because...we didn't give it our best shot? Ugh...I couldn't take that."
Foreshadowing: At the end of each episode of Asia Season 4, they would innocently show the advertisements of the newly built Marina Bay Sands resort in Singapore. As the promo for the final episode rolled in, clips of the promo all point to the resort. Eventually, the final tasks and the finish line all ended at the Marina Bay Sands.
Laser-Guided Karma: Andy and Laura, Asia Season 1 suffered from this. During the first-half of the double-leg in India, Andy & Laura stole a Taxi cab from Sandy & Francesca while they were doing their task. However, towards the very end of the double-leg, Andy & Laura called in a taxi to take them to the pit-stop. Just when they thought that the taxi cab was approaching them, it stopped where Zabrina & Joe Jer was standing and took the girls instead. Ultimately, that's what got the couple eliminated.
Oh Crap: In the second leg of Asia Season 4, Ivan & Hilda arrive at the pitstop location before any other team. Hilda, being her usual bubbly self, doesn't want to run because her legs are sore, so the two walk along the pier where the pitstop is located. Behind them, arriving almost a minute later, are Richard & Richard, who observe the married couple "strolling romantically down the pier" and bolt. Upon seeing the two behind them, Hilda says the trope, and it turns into a footrace for first place. Ivan & Hilda win.
One Steve Limit: Averted, Asia Season 4 had a team whose names are Richard & Richard, Latin America Season 1 had a mother/daughter team who were both named Casilda
Product Placement: The Asian edition is known to make a lot of product placing. Many of the miscellaneous tasks require teams to use a brand-product provided by their sponsors just to do a task or go to another destination. For example, one team member had to take a picture of another team member doing the roadblock or locals singing a traditional song while another team member is recording using a cam-corder.
Shocking Elimination: Jess & Lani, Asia Season 4, were the clear frontrunners going into the penultimate leg, only to fall victim to No Sense of Direction in South Korea and fall hours behind the other teams, after which they were subsequently eliminated.
Shopping Montage: Jess & Lani, Asia Season 4. According to the recap episode, Jess & Lani used their begging and flirting skills to get money just to buy wardrobe. Let's just say they have done this pretty much most the legs.
Why Did It Have to Be Snakes?: Howard & Sahran, Asia Season 1 had their focus entirely on facing their phobias. With the exception of the road block where Howard was required to dive in deep water with the sea animals in Australia, he overcame his fear-inducing tasks without any problems. His partner on the other hand....
At the start of the race, Sahran had a list of phobias. He's afraid of snakes, deep water, public bathrooms and finally heights. During the interview, his childhood trauma of being stuck in a coconut tree had scarred him for life. Well, during their entire duration of their race, Sahran rappelled down from an 8-story building mall in Malaysia, grabbed the clue from a cage full of Anacondas in Indonesia and finally he rock-climbed a cliff at Thailand. As a result, lots of crying ensued. But, hey, at least he did the tasks without quitting.
The Amazing Race Latin America
Action Girl: Renata & Ana Paula in Latin America 4, who became the second team to win the first three legs of the race (After Rob & Amber in All-Stars), and six of the first eight. And are only the second team (after Marc & Rovlison in Asia 2) to put up two streaks of 3+ straight leg wins.
Action Mom: Renata & Ana Paula of Latin America 4. Besides Renata being a fire fighter, the few times they struggle with tasks they repeat the names of their children.
Down to the Last Play: Though the finales in all three seasons of the Latin American version have been pretty close, the second season has the record of being the closest of all the versions of the show. It ended with a boat race and then a sprint to the finish line with only a few yards separating the two teams.
Non-Gameplay Elimination: Perri & Maristela of the Brazilian version, despite being the strongest team in the season, quit the mandatory eating task in the finale resulting in them being disqualified, reasoning that the cold temperature and number of times they were vomiting wasn't worth it.
Oddly Named Sequel: The Latin American seasons: The Amazing Race en Discovery Channel 1, The Amazing Race en Discovery Channel 2, The Amazing Race 3, and The Amazing Race: Edição Brasil (The show had moved to a different channel).
One Steve Limit: Averted, Latin America Season 2 had a father/son team both named Edison.
My Hovercraft Is Full of Eels: One China Detour in Australia 2 (lifted from US Season 14) required teams to listen to customers ordering food in Chinese, then repeat the orders to a chef. It led to the teams saying such phrases as, "Salty fried small tea bag."
Mythology Gag: Australia 2 had a mechanical bull riding task in leg 10, and during the intro to the task they played the Leitmotif used for professional bull riders Jet & Cord in US Seasons 16 and 18.
Reality Show Genre Blindness: All of Australia Season 1's Final 3 teams were blindsided by the Final Exam Finale flag Roadblock in the finale leg, despite it being similar to a rather notable task in US Season 9's finale. The teams even admitted to not bothering to take note of the flags, and struggled enough that any team who had bothered to take notes (a common strategy in the US metagame) probably would have easily won the race.
Shocking Elimination: Australia Season 2 seemed to have this happen every week. Though Adam & Dane ran a rather lackluster two legs, much was expected from them pre-race as they were an alpha male team, and the first season's course had heavily favored such teams. The next three teams eliminated (Sue & Teresa; Kym & Donna; Ross & Tarryn) combined for seven top 4 finishes in the first three legs, and all looked like threats to make the Final 3 prior to their eliminations. Then came Sticky & Sam getting eliminated in 7th, despite having two leg wins, the season's best finishing average, and being the favorites to win before struggling on both halves of the double leg.
Your Princess Is in Another Castle: Used on the racers themselves in Australia Seasons 1 and 2. The teams get a clue telling them to go to mat and find Grant, only to have him tell them that they're still racing, and hand them their next clue.
The Amazing Race Israel
The Casanova: Shay & Guy's (Israel) plan for the race during their introduction was to flirt with the many female teams in competition.
Dumb Blonde: Hadas & Inbal (Israel Season 1) were generally a subversion, but the results of their first task almost played the trope absolutely straight. To explain, during the safari drive task of the first leg, instead of tying their log to the towing hook like everyone else did, they actually tied it to the truck, and to make sure it didn't fall off, they double and triple knotted it; cue them falling from 1st place to 4th place when they try everything they can to get it off, including trying to untie it unsuccessfully, burn the rope, cut it with their leg razors, and eventually smashing a mirror they had with them and using a shard to cut the rope. They lampshaded their stupidity only moments after leaving the task.
Leitmotif: Hannah & Margalit of Israel Season 1 had their own Klezmer-style theme.
Man on Fire: In Israel Season 2, there was a Roadblock where teams had to do a stunt which involved being set on fire.
Non-Gameplay Elimination: Hannah & Margalit of the Israeli version were forced to quit the race after Margalit suffered a severe abdominal infection in leg 5 and was rushed to hospital. She recovered soon after they were removed from competition, and thus were able to return for the finale.
Sequel Escalation: The Israeli version. While the first season was fairly standard, the second season had more challenging tasks (the very first thing teams had to do at was climb rope ladders to their cars which were each suspended by cranes) but was also longer both to the racers (13 legs compared to 10) and to the viewers (28 episodes compared to 20. There was even one episode that was entirely devoted to the teams getting from the final clue to the Pit Stop!)
Book Ends: The Race started and ended in the Toronto Region.
Canada, Eh?: Averted, as the whole goal of the first season was to give people a greater appreciation of their own country.
Chekhov's Gun: Each clue at the start of each leg had a flag of the destination province while the greeters at the end of each leg (including the Chocolate Task judge in the final leg) were each wearing their respective provincial flowers. Only 1 team remembered this detail and vaulted them from last to first to win the race.
Drill Sergeant Nasty: The RCMP task judge, who chewed out Jet for his sarcastic attitude and reduced Celina to tears.
Face Your Fears: The first task involved teams reaching in terrariums filled with animals for clues. The teams who grabbed clues out of the terrariums with the scarier animals (snakes, spiders, rats, and scorpions) got on the better flight.
Mythology Gag: When teams completed the Country Line Dancing Roadblock in Calgary, the show played Cowboys Jet & Cord's Leitmotif from US Seasons 16 and 18.
Action Girl: Beauty Queens Valeria & Bohdana from Ukraine 1, who rattled off five straight victories to win the season, and set the record for the best finishing average of any female team in any version.
Book Ends: The Norwegian version began and ended at Holmenkollbakken in Oslo.
The Cameo: Rick from the first season of China Rush handed out clues in a Roadblock in China Rush 2.
Chekhov's Skill: Subverted in China Rush Season 1, where in the first leg Rick & Josh were the only team that couldn't figure out how to use a ticket dispenser and had to find someone to help them. Later in the final leg when they had a large lead, not understanding the ticket dispenser caused them to miss a train and allowed the other teams to catch up.
Perpetual Frowner: Ryan (China Rush 3), to the point that other teams jokingly try to get him to smile.
Read the Freaking Clue: The most painful example of this in the series had to have happened to Phuc Vinh & Linh Chi in Vietnam Season 1. In the final leg, they arrived at the Finish Line 1st and would have won, except they were issued a 30-minute penalty for using notes during a task and violating traffic regulations. While serving their penalty, Lam Anh & Thu Hien checked in and were declared the winners.
Theme Twin Naming: Played straight with Khai Shing & Khai Sheng of China Rush 3; averted with Frank & Ivar (Norge).
