Never Forget Kat Dunn's Ability To Turn A Phrase On Big Brother 21

Kat Dunn saw the block more than once on Season 21 of Big Brother, but she managed to stay in the house long enough to make it to the Jury.

While she did a great job of befriending everyone in the house and playing a game involving secret allies, Kat made no secret of her many, ahem, abstract thoughts. Viewers and Houseguests alike came to love Kat's singular personality and her unique ways of expressing herself. 

Here are some of Kat's best views, notions, revelations, and, of course, conspiracies as only Kat could say them.

It's one thing to be paranoid of your fellow Houseguests in the Big Brother house. After all, this is a game.

Kat, however, took paranoia to new heights every time she told the others about the conspiracies she believes are in play in the world outside the BB house. Ironically, even conspiracy theorists seem to have their limits.

Facing your fears is certainly a part of playing the Big Brother game. Leave it to Kat, however, to reveal a fear that left her fellow Houseguests baffled.

Kat shared that she'd rather throw a competition than be faced with the prospect of eating those small, blue, harmless pieces of fruit.

While confidence will get you far in Big Brother, acknowledging you don't know what you don't know may just be the mark of a truly genius player. 

Kat was always quick to assert her doubt. Or as some might say: a genuine understanding of the deceptive nature of the game.

Strategy shmategy. Sometimes putting on blinders, charging headfirst, and seeing what happens is the winning technique. 

Kat proved herself capable of surprising even herself, all while showing up her fellow Houseguests and getting ahead in the game.

Whether she wanted to intimidate her fellow Houseguests or mislead them as to where her talents lie, Kat was known to drop that she was a part of the famed club for geniuses, Mensa. 

Of course, she later admitted she might be in a more suspicious, lesser-known faction of Mensa.

Kat was never shy when it came to matters of the heart and she made no secret of her crush on BB20's Brett Robinson.

When Holly pretended to take her on a date as Brett's cousin, she played along with hilarious enthusiasm.

Kat's favorite saying proved her suspicious but good-humored character. If you've heard her say it once, you've heard her say it a hundred times.
