One Tuesday afternoon, Little Jonny decides he wants extra homework, so he went to his teacher and said, "Hello, can I have extra homework this week?"
The teacher replied with, "Sure, be at my house Friday afternoon to cut my lawn, polish the counters, scrub the baseboards, scrub and paint the walls!"
And Johnny replied with, "That's not what I meant, but at least I'll get paid!"
The teacher said, "How about $200 each job?"
Johnny replied with, "OK."
Friday afternoon at her house, after Johnny does all the jobs, he asked for his payment and the teacher laughed and said, "You do know that Tuesday was April Fools' Day, right?"
