Fisrt off, let's start with what we know:
Barney = CUTE PURPLE
DINOSAUR
Then, because when dealing with evil you have to use dead languages, we'll change all the U's to look like V's:
Barney = CVTE PVRPLE DINSAVR
Then we extract any letter that could be a Roman Numeral:
Barney = C V V L D I V
Almost there - change the
roman numerals to
arabic:
Barney = 100 + 5 + 5 + 50 + 500 + 1 + 5
And then we add the numerals to get, yep, you guessed it -
666!
