==Explanation==
{{incomplete}}

[[White Hat]] is explaining to [[Cueball]] a program he wrote, the "Ayn Random Number Generator", which is a pun on {{w|Ayn Rand}}, the name of a writer who created a philosophical system known as {{w|Objectivism (Ayn Rand)|Objectivism}}. Objectivists believe that the primary aim of life is to maximise personal happiness. In their view, if some humans are born more capable of satisfying their desires than other people, they deserve to reap greater rewards from life than others. In the comic, White Hat uses a similar line of reason to justify some numbers appearing more often than others in a {{w|Random number generation|"random" number generator}}.

The title text identifies a group of people whose names match the {{w|regular expression}} <code>/(\b[plurandy]+\b ?){2}/i</code>. A step-by-step explanation of the expression:
*\b is a word boundary, matching anywhere there is a 'word character' next to a non-word character&mdash;punctuation, digit, spacing, etc.
*[plurandy] is a character class, and will match any single character from the set inside the square brackets
*the plus sign means ''one or more'' of the previous thing, so [plurandy]+ matches one or many of the characters in that class, one after the other
*" ?" - a space followed by a question mark:  "?" means "0 or 1 of the previous thing", so a space is optional
*the whole section in parentheses (\b[plurandy]+\b ?) translates to "a word containing one or more letters, all of which are in the set [plurandy], followed by an optional space"
*the {2} on the end means to repeat the pattern, so it must match exactly twice
*The slashes at each end mark out the pattern, and the "i" at the end is an expression qualifier means it is "case insensitive" (uppercase and lowercase match interchangeably)

Overall, it matches two words separated by a space, composed entirely of the letters in [plurandy], which is what all the names listed have in common.

:Cueball: This Ayn Random number generator you wrote ''claims'' to be fair, but the output is biased toward certain numbers.
:White Hat: '''''Well, maybe those numbers are just intrinsically better!'''''
