10 - kim johnson's immunity win streak
For almost the entirety of Africa, we watch kim j be corralled off onto the sidelines by the boran 3, but this hag had bigger plans up her sleeve. we all knew that if kim didn't win the next two immunities, she's dead. so she steps her ass up and wins the f4 fallen comrades challenge in a blaze of glory, manipulating Jeff probst into not giving lex a point, and then proceeding to vote off the nasty that was big tom.
at f3 she then keeps her hand on an idol for 3 hours, and in a perfect editing moment, we watch as she cooly stares down lex until he collapses with stomach cramps ( him mentioning how diarrhea would kill him in the first episode only for it to actually do so in final immunity also contributes to this). now, kim not only proves that old ladies can win immunity challenges, she also prevents two nasties; lex and tom, from winning survivor, further making these wins even better.
in the end, she could not defeat king Ethan, but the way she came out of nowhere to literally snatch the boran 3 bald was so good, and worthy of top ten status.
