In season 6, episode 12 of spongebob they are doing an hour long special. At one point they get stuck in the air ducts, and Spongebob announces that he memorized the ducts and makes a pattern on his back. It looks an awful lot like a doom level. I checked some resources and e1m3 and e3m3 are the closest, but nothing is an exact match.
Does anyone recognize this layout, or is it just a weird coincidence?
