As of 2013, this episode has the longest title in the series. The shortest title is a toss-up between season 12's "HOMR" and season 25's "YOLO".
Although Grampa's military unit was known as the "Flying Hellfish", both the elaborate headstone and stationery letterhead read "Fighting Hellfish."
Mr. Burns is shown to have the strength to kick Bart halfway across his and Grampa's boat. This is inconsistent with his appearances in other episodes, where he is extremely weak and tires easily, though he could have summed up all his energy just to do that.
