21 surprising things you didn't know about 'Big Brother'

CBS adapted the Dutch reality show's format when it started gathering big ratings in Germany and Spain as well, according to SF Gate.

"Big Brother" has taken place in India, Australia, Brazil, the UK, Africa, Italy, Saudi Arabia, Canada, and more, according to ET Canada.

CBS pays its houseguests for taking the summer off for the show, which isn't the case with every reality show.

According to Reel Rundown, the weekly stipend for "Big Brother" houseguests is $1,000. This information was obtained during season 19 of the show when two contestants, Jessica Graf and Cody Nickson, were overheard discussing their finances.

In the past, a reported "Big Brother" contract obtained by Reality Blurred in 2011, said houseguests make $750 per week for as long as they're still in the game.

Host Julie Chen bragged about this stat to Entertainment Tonight in 2018, and she's right.

Only season 17 Bachelor Sean Lowe married his winner — meanwhile, five "Big Brother" couples have already gotten married and another is currently engaged.

Tests of endurance are common on the show, but one competition stretched on for over 14 hours.

The season-six Head of Household competition required contestants to hold down a button. If you let go, you were out.

According to CBS, it went on for 14 hours and 37 minutes, and no one won until 9 a.m. the next day.

"Big Brother" season-15 winner Andy Herren told HuffPost that production would "blare pop songs in the morning to wake you up. It could be any time between 8 a.m. and 11 a.m."

The show's name comes from the book's leader, Big Brother, who watches over citizens at all times via telescreens.

It's a fitting name, but it's not the only "1984" reference. The show also has a stuffed animal owl that chills in the house named Orwell after the author.

The owl even has his own Twitter account.

Chen told Entertainment Tonight in 2016 that 87 cameras and 110 microphones are picking up what the contestants are doing and saying at all times.

There's no privacy in the "Big Brother" house.

SF Gate reported that there is a camera installed in the houseguests' bathroom, but that footage isn't shown on air or on the feeds.

Producers told SF Gate that the camera was there just so contestants couldn't collude in secret. But the bathroom camera footage has been used on TV at least once.

On season two, Shannon Dragoo took Hardy Ames-Hill's toothbrush and scrubbed the toilet with it out of anger. The footage was eventually played for the audience, and Shannon was made to apologize and give Hardy a new toothbrush.

Usually, the only way out the "Big Brother" door is if your fellow houseguests evict you — but CBS also doesn't tolerate violence or disobedience.

As CBS News reported, over the years, a handful of houseguests have been expelled from the show.

This includes Justin Sebik from season two, who pulled a knife on a fellow contestant, and Chima Simone from season 11, who threw her mic in the pool after repeated requests from production to put it on.

If houseguests slip up, they'll be reminded with a stern, "Please. Stop. Singing."

This rule likely has to do with copyright concerns, since CBS would have to pay to air a segment that contained an artist's song.

In the diary room, where contestants go to speak to cameras away from their fellow houseguests, many secrets are revealed. But sometimes producers want a bit more energy.

In a Reddit AMA, former season-19 contestant Cody Nickson said showrunners would ask "me to say something again 'but with more excitement this time'".

He said he refused to do so.

Michelle Meyer, who competed on season 18 of the show, replied to his comment saying, "I wish I did this".

Entertainment Weekly reported that during season-two production told the houseguests about the September 11 attacks since houseguest Monica Bailey's cousin was listed as one of the missing World Trade Center workers.

During the online season, "Big Brother Over the Top," the houseguests were informed of Donald Trump's presidential victory.

If you've ever spotted a random fake squirrel in a "Big Brother" competition, that's Benny. Keep an eye out for him in the future.

It's an elaborately set up soundstage, according to Reality Blurred.

And although it may look real to those watching, season four's Erika Landin told HuffPost that it doesn't seem that real to those playing the game.

"It doesn't really feel like a house. It actually feels you're living on a set," she said. "The whole ceiling is television lights."

People have flown banners over the backyard and yelled over the wall to try to reach out to those playing.

If this happens, houseguests are instructed to go inside until the situation has been dealt with so as to avoid any outside influence on the game.

As with many reality TV shows, production doesn't rely on self-submissions alone.

The show rounds out their applicant pool with people of their choosing. HuffPost reported that season six's James Rhine was one such recruit.

"They found me on MySpace. They literally hit me up because they liked the modeling picture I had as a profile picture, and my old job was as a corporate investigator," he said. "I had never watched the show, but they kept telling me they saw me as the second coming of this Dr. Will person."

The first pair to do this was Amanda Craig and David Lane on season four, according to Vulture.

They may have pulled the covers over their heads, but they weren't that sneaky about what was going down underneath.

"I'm a grown man and grown men do grown-up things, " David told the cameras following the incident.

Before season seven, when the oatmeal-y gooey slop was introduced, contestants were punished by being made to eat only peanut butter and jelly sandwiches.

If contestants make it far enough in the game, they can go to the jury house. These eliminated houseguests later decide who wins between the final two players.

But until their important role comes up, they just have a great time. With no cameras, the pressure is off and contestants can finally let loose and have fun.

As season four's Jack Owens said to HuffPost, "It was a vacation in a millionaire's home on the Pacific Ocean. We had all the beer we wanted. We had all the freedom we wanted … I was allowed to occasionally talk to my wife on the phone. The game was off. We partied together and enjoyed each other."

There wasn't a Head of Household or a Power of Veto and the evicted houseguest was chosen by viewers' votes.

Good thing CBS changed it up, because since then it's been going strong for over 20 years. Here's to many more dramatic seasons to come.
