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.
1. Rachel Swindler – Big Brother Season 20

“My stomach is as dark as Bay,” she said.
2. Angela Rummans – Big Brother Season 20

While viewers never got to see the duo getting a warning from CBS, Angela was seen on the live feeds crying.
3. Kaitlyn Herman – Big Brother Season 20

Another instance that landed her in hot water found her using the N-word while quoting Drake’s “0 to 100.”
4. Paul Abrahmian – Big Brother Season 18 & 19

He went on to say that his makeup was called “blackface.” Yikes.
5. Jason Dent – Big Brother Season 19

He was not ejected from the show.
6. Frank Eudy – Big Brother Season 18

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.
