A vital new understanding of Eschatology came to my desk

1. Start with the given: CUTE PURPLE DINOSAUR
2. Change all "U's" to "V's" (which is proper Latin anyway)
CVTE PVRPLE DINOSAVR
3. Extract all Roman Numberals:
CV LV DIV
4. Convert these into Arabic values:
100 5 5 50 500 1 5
5. Add these numbers up = 666

There you have it, proof that Barney is the Antichrist!
