The CEO of the transcription company Verbal Ink was so enthused by Lost that he purchased and installed Jacob's candidate wall at the group's office. Hopefully the wall is used as an ominous means to relay employee firings and promotions.
Also, according to the company, "Don Knotts" is among the many names etched on the wall. If Barney Fife had appeared from beyond on the grave on the Lost finale, all the pressing questions would have been answered! Hat tip to Zach.
