A young schoolboy was having a hard time pronouncing the letter R, and all the other kids were, of course, teasing him about it. To help him out, the teacher gave him a sentence to practice at home: Robert gave Richard a rap in the ribs for roasting the rabbit so rare. In class a few days later, the teacher asked the boy to recite the sentence out loud. The boy nervously eyed his classmates–many of them already laughing at him–then replied, Bob gave Dick a poke in the side because the bunny wasnt cooked enough.
