The argument "pro pink pants" runs like this :

[06:56] <@shocktrooper1> cordoroys are evil!
[06:58] <@shocktrooper1> what is more scary, a gnome with blue pants or a gnome with brown pants?
[06:59] <@shocktrooper1> wrong!
[07:24] <@eihrul> pink pants, obviously
[07:27] <@shocktrooper1> arrgh.   that was a lucky guess
[07:29] <@eihrul> it's obvious
[07:29] <@eihrul> who has ever seen a gnome with pink pants?
[07:29] <@eihrul> nobody!
[07:29] <@eihrul> so if you see one, you know some shit's really wrong
