Survivor is well known for its shocking moments, and the long-running reality series has racked up several over the course of its 27 seasons.

In the very first season, Survivor: Borneo, viewers were transfixed when Sue Hawk gave a vicious jury speech to the final two competitors, Richard Hatch and Kelly Wiglesworth. The speech is best known as the "Snakes and Rats Speech."

A season later in Survivor: The Australian Outback, Michael Skupin proved how real the show was in reality after falling into a fire and burning his skin. 

Survivor: Amazon watchers can easily remember the challenge in which Jenna Morasca and Heidi Strobel stripped naked for peanut butter and chocolate, proving how desperate they had become for food.

In Survivor: Pearl Islands, the infamous Jonny Fairplay and his visiting loved one cooked up a lie that his grandmother had died, allowing him to gain sympathy with his tribe.

Survivor: China featured a surprisingly ill-conceived move after James Clement was voted out despite having two Immunity Idols in his pocket that he could have played.

An even dumber move occurred in Survivor: Micronesia when Erik Reichenbach gave away his Immunity Necklace and was subsequently voted out by his tribe.

Survivor: Samoa was heavily focused on the infamous Russell Hantz, but viewers were shocked when it was the timid Natalie White who defeated him in the end.

In Survivor: Heroes vs. Villains, Sandra Diaz-Twine became the first ever two-time winner after her victory in Survivor: Pearl Islands.

Finally, this season of Survivor: Blood vs. Water featured a huge moment in which Ciera Eastin decided to vote out her own mother Laura Morett in order to further her game.
