Person A: Man, that nutcase Martin Bryant guy shot 35 people in Tasmania!

Person B: No, he wasn't a nutcase, that was just a psyop so the government could have an excuse to ban guns.

a high official in the Ministry of Love in "1984." He tortured the protagonist, Winston Smith, into submission to the totalitarian "Party." O'Brien was played in the film by Richard Burton; it was Burton's last role.
Winston was struck, as he had been struck before, by the tiredness of O'Brien's face. - George Orwell, "1984"

a white suprecemacist leader that George Costanza impersonated to get a free ride in a limo. George's lie nearly cost him his life, as he faced being torn limb-from-limb by an angry mob, or being shot by angry neo-Nazi's.

We're not sure how he got out of this dilemma, as the show ended with him still in grave danger, but he seemed okay in the next episode.

originating in Middletown, Rhode Island, O'Brien is arguably one of the worst math teachers to ever live. He style, looks, and personality are some of the worst you will ever see. His teaching style consists of going over the material until he remembers how to do it well enough to grade a quiz, then quizzing. Whether or not his students understand it means nothing to him, and for this reason he is possibly the most hated teacher on the whole Aquidnick Island.

Extremely fond of the number "0", as it is the only grade he enjoys giving.

Also known to creep on certain innocent girls through entire class periods/school years
Student A- Fuck man, I have O'Brien for Honors Algebra II!
Student B- Oh, dude, that blows. Enjoy failure...

O'Brien- So you put this here, and don't skip steps, OR ITS A ZERO! Oh wait, I did it wrong...and I skipped a step...ITS STILL A ZERO FOR YOU!

Student 1-Wait, I don't understand this, could you go over it?
O'Brien-NO! Quiz time!
