"One Friday morning" joke

One Friday morning, a teacher came up with a novel way to motivate
her class. She told them that she would read a quote and the first
student to correctly identify who said it would receive the rest of
the day off.
She started with "This was England's finest hour." Little Suzy
instantly jumped up and said, "Winston Churchill."
"Congratulations," said the teacher, "you may go home early."
The teacher then said, "Ask not what your country can do for you,
but.." Before she could finish the quote, another young lady belts
out, "John F. Kennedy!"
"Very good," says the teacher, "you may go also."
Irritated that he has missed two golden opportunities, Little Johnny
said, "I wish those girls would just shut up."
Upon overhearing this comment, the outraged teacher demanded to know
who said it. Johnny instantly rose to his feet and said, "Bill
Clinton. I'll see you Monday."
