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 wasn't cooked enough."
