One day the teacher asked the class, what does the chicken give us?
Little Johnny raised his hand and said, eggs.
Very good Johnny, says the teacher. Now what does the pig give us?
Little Johnny got confused and wasn’t sure.
Little Timmy raised his hand and said. Bacon.
Very good said the teacher.
Little Timmy said, see Johnny if you did your homework you would have known.
Then the teacher said, alright class I have a surprise for whoever answers this question correctly. What does the fat cow give us?
Little Johnny eagerly anticipating his surprise raised his hand.
Yes Little Johnny what does the fat cow give us?
Little Johnny answered, homework.
