Big Brother has been on the air since the year 2000.
It is filmed 24 hours a day, and fans are able to watch a live feed online that keeps them up to speed with what happens inside the house when the show is not airing.
That means some of the houseguests forget their surroundings and say some crazy things.
What about the others?
Well, some of them did not seem to care and had no filter.
We've rounded up the most controversial houseguests below.
Rachel Swindler - Big Brother Season 20
Viewers who watched the Big Brother live feeds were shocked when Swindler compared her tan to her black fellow houseguest Bayleigh Dayton.
"My stomach is as dark as Bay," she said.
Angela Rummans - Big Brother Season 20
Angela was also part of the conversation about Swindler about skin color and said the following: "I’m looking ghetto here with the skin coloration.”
While viewers never got to see the duo getting a warning from CBS, Angela was seen on the live feeds crying.
Kaitlyn Herman - Big Brother Season 20
Herman's stint in the house resulted in her boyfriend apparently cutting ties with her. She was all over Tyler Crispen, Brett Robinson and Faysal Shafaat.
Another instance that landed her in hot water found her using the N-word while quoting Drake's "0 to 100."
Paul Abrahmian - Big Brother Season 18 & 19
Paul dressed in black facial cosmetics as he targeted black houseguest, Dominique Cooper for eviction.
He went on to say that his makeup was called "blackface." Yikes.
Jason Dent - Big Brother Season 19
Jason shocked live feed viewers with his comments about raping fellow houseguest Kevin Schlehuber's wife after tying up all of his daughters and making them watch.
He was not ejected from the show.
Frank Eudy - Big Brother Season 18
Eudy went too far when he groped Da'Vonne Rogers, and called her a "slut."
Understandably, it all got too much and Da'Vonne hit up the diary room to let viewers know how she felt.
“I don't want my daughter to see that and think it's OK for guys to hit girls on their butts and guys to call girls sluts,” she sobbed.
Aaryn Gries - Big Brother Season 15
Gries felt the ire of host Julie Chen when she referred to Asian people as "squinty-eyed," and even told Korean houseguest Helen Kim to "go make some rice."
Spencer Clawson - Big Brother Season 15
That same season, Clawson stirred up controversy by praising Adolf Hiter's speaking abilities. Yeah, we're not sure why we still watch this show.
Willie Hantz - Big Brother Season 14
Hantz was a livewire who found himself expelled from the house early in the season. He called his fellow houseguests names, threw food, and even head-butted Joe Arvin.
Jeff Schroeder - Big Brother Season 11 & 13
Jeff was shocked when he was told that J.K. Rowling considered Harry Potter character Albus Dumbledore to be gay.
“I don’t think it’s the right thing to have a little kids’ book and have the headmaster that you’re locked away with in a magical land be gay,” he said.
Braden Bacha - Big Brother Season 11
Bacha made multiple racist and derogatory comments to fellow houseguests, but he later claimed to Reality TV World that "it was out of no malice whatsoever."
Adam Jasinski - Big Brother Season 9
Adam was a real loser, and we cannot believe he actually won the $500k. He worked for an autism foundation and said that he planned to spend his winnings on a hair salon "so retards can get it together and get their hair done."
He subsequently said he would donate $100,000 to Autism United, but he was fired from his job.
Amber Siyavus - Big Brother Season 8
Siyavus showed off her true personality when she called Jewish people "bad" and claimed, "You can tell by their name, you can tell by their nose."
Yeah, we're surprised she was not kicked out of the house.
Justin Sebik - Big Brother Season 2
Big Brother hit the headlines for all the wrong reasons thanks to Sebik. He held a knife to a fellow housemate's throat.
Thankfully, he was kicked out of the game.
JC Monduix - Big Brother Season 20
And another one from Big Brother Season 20 makes the list!
JC went from
