Take the phrase: CUTE PURPLE DINOSAUR
Now, in Latin, U's are more properly V's, so chanve them all: CVTE PVRPLE DINOSAVR
Now, we will extract all the Roman Numerals, and disregard the rest of the letters, you will get this: C V V L D I V
Now, add them together: 100 + 5 + 5 + 50 + 500 + 1 + 5
What is the answer? 666. Thus, Barney the "Cute Purple Dinosaur" is truly Satan on earth
