15 surprising things you didn't know about 'Survivor'

Although "Survivor" is technically reality TV, there's a lot you don't see when the cameras stop rolling.

For instance, after host and producer Jeff Probst tells the tribes about the daily challenge, he and challenge creator John Kirhoffer walk through the challenge with each tribe, giving them the opportunity to strategize before it actually begins, according to Today.

The idea for "Survivor" was first created by producer Charlie Parsons in 1992 for a UK production company, but the first-ever "Survivor" series to debut on TV was in Sweden.

The show, which first aired in 1997, was called "Expedition Robinson."

Although "Survivor" is all about survival, that doesn't mean the show is immune from love arcs.

In its multi-season history, "Survivor" has seen its fair share of couples, including Rob "Boston Rob" Mariano and Amber Brkich, who fell in love on "Survivor: All-Stars."

The two ended up going head-to-head for the $1 million prize, with Amber winning it all.

The two later married and have since had four children. They are also the only "Survivor" couple to have each won individual titles as "Sole Survivor."

The Dream Team is a group of 20-somethings who test out the challenges before contestants compete in them.

In a behind-the-scenes CBS video, Probst said this group of 16 to 20 people also helps build and paint the challenges.

The youngest contestant on "Survivor" was Will Wahl, who was 18 years old when he appeared on Season 33: "Millennials vs. Gen X."

Meanwhile, the oldest contestant to ever appear on the show was former Navy SEAL Rudy Boesch, who starred on the first and eighth seasons of the show at ages 72 and 75, respectively.

Speaking of age, the youngest person to ever win survivor was Jud "Fabio" Birza who won "Survivor: Nicaragua" at 21 years old.

On the flip side, the oldest person to win "Survivor" was Bob Crowley, who was 57 years old when he brought home the cash prize.

Executive producer Mark Burnett has admitted to reenacting certain scenes on "Survivor" to get a better shot, per ABC. The show has even been known to use body doubles for this same reason.

Seeing "Survivor" is a "reality" show, many people have found these reenactments a bit ... unreal.

In its almost 20 years on air, "Survivor" has had 13 people quit the show. The most recent was two-time winner Sandra Diaz-Twine who quit during season 40, Winners at War.

Although each reasoning is different, host Jeff Probst has a very well-known distaste for people who quit the show, per a 2015 interview with Entertainment Weekly.

Only two people have won the survival game twice: Sandra Diaz-Twine and Tony Vlachos.

Everyone gets a certain amount of compensation, with the people who last the longest getting the most money.

Per Today, the second-place player gets $100,000 and the person who comes in third receives $85,000.

"Survivor" legend Ozzy Lusth, has a few records to his name.

He is one of few people to have played "Survivor" four times and he is the only competitor to have been voted off three times in a single game.

Until recently, he'd spent the most time as a contestant on the show with 128 days total,

Casting director Lynne Spillman told Today in 2008 that the show frequently casts models and actors as contestants on "Survivor."

Although they still go through the rigorous casting process, these recruits are sometimes chosen due to a lack of qualified applicants in a given year.

Only one person in "Survivor" history has attended and survived every tribal council on their season and that honor goes to season 25's winner Denise Stapley.

And, speaking of impressive wins, both season 18's JT Thomas and season 26's John Cochran have played "perfect games," meaning they won the final tribal councils with a unanimous vote and didn't have anyone vote against them throughout the entire game.

Celebrities are heavily invested in the "Survivor" franchise.

Musician Sia donated $100,000 to her favorite player, season 32's Tai Trang, and Tyler Perry was the genius behind season 28's shocking immunity-idol twist.

In addition, some stars have played as contestants, including baseball player John Rocker, "Facts of Life" star Lisa Whelchel, and football player Brad Culpepper.

In a 2013 interview with Archive of American Television, Probst said he faced off against "The Amazing Race" host Phil Keoghan for the title of "Survivor" host.
