They’ve spent up to 17 seasons on their own deadlines, pushing animation to the limit to bring you a fresh new episode of South Park.

In the 2011 documentary, South Park, 6 Days to Air, you saw how creators Matt Stone and Trey Parker made it all happen. This week, the dynamic duo finally blew a deadline and failed to submit their half-hour episode to Comedy Central in time for last night’s airing. Blame it on the electricity. Or lack thereof.

South Park Studios announced Wednesday that a power outage Tuesday night shut down its computers and animators who were working on editing, rendering and sound issues to complete the episode, “Goth Kids 3: Dawn of the Posers.”

“It sucks to miss an air date but after all these years of tempting fate by delivering the show last minute, I guess it was bound to happen,” Parker said.

Comedy Central instead inserted a repeat last night and had Parker and Stone provide live-Tweet commentary.

“Goth Kids 3: Dawn of the Posers” will air next Wednesday, Oct. 23rd. They had made enough headway by Monday to submit a teaser clip for Comedy Central to promote the “Goth Kids 3” episode. You’ll just have to remain teased for another week.

For another look at how Matt & Trey and the gang make their episodes in six days, just like God, check out this day-by-day storyboarding from 2008’s “Super Fun Thyme” in Six Days To South Park.

There’s also the great 2011 documentary, 6 Days to Air, which is available as part of the 15th season DVD set.
