(Protip: to defeat the Machine Nun, shoot at it until it dies. Although you may have to kill John Romero first, somehow).
Incidentally, today a person walks into chat after not having been on 'chat for a while and makes his typical entrance line ("I have arrived!") in English for a change rather than really godawful weeaboo Japanese directly yoinked from an anime without realizing that it uses the most arrogant possible way of saying it. Something to the line of "Ore Sanjo". Which instantly jumped into my brain and mutated into "Ore Banjo!"
Because Weeaboo Rednecks is the BEST mental image EVER when I'm half asleep.
"Gosh darn, that there lil' fella is just so kawaii!"
"Well bust mah britches an' call me streaker, that there seems more sugoi than kawaii!"
"... Well, shucks, you're right, Bubba-chan!"
... And then they're all gunned down by the machine nun from earlier. High caliber rounds, designed to make its targets holey.
