Who Said That

A teacher decides to let students out early if they can name the origin of a famous quote.
Teacher: "Who said 'Four Score and Seven Years Ago’?”
Johnny began to open his mouth, but Susie says, "Abraham Lincoln.”
Teacher: "That's right Susie, you can go home.”
Teacher: "Who said 'I Have a Dream’?”
Again, before Johnny can open his mouth, Mary says, "Martin Luther King.”
Teacher: "That's right Mary, you can go.”
Teacher: "Who said 'Ask not, what your country can do for you’?”
Before Johnny can open his mouth, Nancy says, "John F. Kennedy.”
Teacher: "That's right Nancy, you may also leave.”
When the teacher turns her back Johnny says in frustration,
"I wish these dumb bitches would keep their fucking mouths shut!”
The teacher turns around and she is livid: "NOW WHO SAID THAT?!?!”

Johnny: "Harvey Weinstein. Can I go now?”
