I have a few shocking ones from each season except for season 2 - 4 (haven't had time to watch those seasons)
TAR1- Nancy & Emily
- cool underdogs in beginning, but treated each other horribly as the race progresses
TAR5- Jim & Marsha
- I loved them in the start of the race, but Marsha turned into a horrible race partner after Uruguay
TAR6- Jon & Victoria
- Loved their dysfunctionality from the first two cold episodes, but then it just got annoying and turned into a brawl against each other.
TAR7- Lynn & Alex
- I loved their personality in the beginning of the race, but they got a bit annoying as the race progresses
TAR8- Godlewski sisters
- Happy when they got 1st on the first leg like Debbie & Bianca, bur did not live up to the lifelong friends' standards. Happy-go-lucky attitudes made them look cocky
TAR9- BJ & Tyler
- I thought I would love them, but their jokes got so "funny", they got horrible in my opinion to watch.
Jus' sayin'... :cmas30.
TAR10- Tyler & James
- I loved watching them race in the first 5 legs, but they were running it with rather weaker jokes and I ended up disliking them when they won. Sorry, but I am not the biggest model winners.
TAR11- David & Mary
- Loved them in the first two episodes until they figured they "ain't gonna help anybody" and Mary started bitching about tasks like "I CAIN'T DO A FORDY FOOT ROCK CLIMB!"
TAR12- Shana & Jennifer
- I loved them at first, but then they became these drama queens and they began to get on my last nerves with their bratty behavior.
TAR13- Terence & Sarah
- One of the nicer coupled, but Terence wad just afraid of doing everything making Sarah do most of the correct work... speeding... tsk tsk
TAR14- Margie & Luke
- I loved their family bonds in the race, but I didn't like Margaret's confrontation with Kisha & Jen in Guilin. Made me dislike her more, Luke not very big downfall.
TAR15- Sam & Dan
- Fun guys at first, but turned into "fungi" after bickering over the edge.
TAR16- Steve & Allie
- Sorry, I love these two as family and people, but as racers, I wasn't feeling much of them, they were pretty overrated as being a rather boring team that season.
The rest can be remained a mysterious, I'm tired of long descriptions.
TAR17- Jill & Thomas
TAR18- Flight Time & Big Easy
TAR19- Ernie & Cindy
TAR20- Art & JJ
TAR21- Gary & Will
