I once had the mispleasure to face a Bash script that was 35 lines tall but over 800 columns wide. The bulk of it was a two-dimensional array -- or rather, a behemoth that behaved like an array of arrays -- with way, way too many fields.
If that wasn't bad enough, my code review to essentially rotate the table 90 degrees was rejected because -- and I kid you not -- the change was unreviewable in any of our tools and thus deemed too risky to change. /facepalm
