Krazy Lights!!!
 

The overhead lighting system was mis-wired on my side of the first class cabin on flight DL 1104 HNL-SLC 18 July 11. My light switch controlled the light 2 rows in front, the light switch of the passenger in front controlled someone else's overhead light, etc. Very frustrating not being able to read during a night flight! One of the attendants offered me Frequent Flyer miles as compensation, but 1,000 miles is insufficient!

Very odd indeed. Especially since all seats are independently wired.
