Barney is Satan

MATHEMATICAL PROOF (as in Geometry)
REQUIRED TO PROVE THAT "BARNEY IS SATAN"
Given: Barney is a cute purple dinosaur
Prove: Barney is Satan

Step 1: The Romans had no letter "U" so they used "V'' instead for printing.

Therefore, the Roman representation for Barney would be CVTE PVRPLE DINOSAVR

Step 2: Taking CVTE PVRPLE DINOSAVR, and extracting the Roman neumerals, we have:

C V V L D I V

Step 3: The decimal equivalent of these Roman neumerals would be:

100 5 5 50 500 1 5

Step 4: Adding these numbers together would produce:

666

Step 5: 666 is the number of the beast

Therefore: Barney is Satan Q.E.D.
