Here's a review of high school geometry. Hope it doesn't bring back too
many nightmares!

Given: Barney is a CUTE PURPLE DINOSAUR
Prove: Barney is Satan

The Romans had no letter "U" and used "V" instead for printing, meaning
the Roman representation for Barney would be: CVTE PVRPLE DINOSAVR

Extracting the roman numerals, we have:
          C   V   V   L   D   I   V

And their numerical equivalents are:
          100   5   5   50   500   1   5

Adding those numbers produces:
          666

666 is the number of the Beast, as stated in Revelation.

Proved: BARNEY IS SATAN!
