R is an awesome letter, and it is so popular among textbooks! The R is like P, but with an awesome serif added towards it. That's what makes it super awesome! Remember, kids, don't try this at home! Why? Because Rs have super ninja robot lasers that blast any intruders. But they've only blasted 3 people: Carl, for not delivering his horoscope, Trixie, for posting a Gangnam Style image on his Facebook page, and Frankenbooger, for, well, because he has "booger" in his name.
