Johnny in the last class before Christmas

It's the day before Christmas break. The students have turned in all their work, and there is really nothing more to do. The children are so restless the teacher decides to have an early dismissal.
Teacher: "Whoever answers the questions I ask, first and correctly, can leave early today."
Little Johnny says to himself: "Good, I want to get outta here. I'm smart and will answer the question."
Teacher: "Who said 'Four Score and Seven Years Ago'?"
Before Johnny can open his mouth, Susie says: "Abraham Lincoln."
Teacher: "That's right Susie, you can go home."
Johnny is mad that Susie answered the question first.
Teacher: "Who said 'I Have a Dream'?"
Before Johnny say a word, Mary says: "Martin Luther King."
Teacher: "That's right Mary, you can go."
Johnny is even madder than before.
Teacher: "Who said 'Ask not, what your country can do for you'?"
Before Johnny gets his mouth open, Nancy says: "John F. Kennedy."
Teacher: "That's right Nancy, you may also leave."
By now, Johnny is boiling mad that he has not been able to answer to any of the questions.
When the teacher turns her back, Johnny says: "I wish these bitches would keep their mouths shut!"
The teacher spins around: "NOW WHO SAID THAT?"
Johnny: "TIGER WOODS!!! Can I go now?"
