The sudden swap of the last episode to scenery footage came as a shock to many fans, but amidst the outrage, a 4chan contributor commented "Nice boat." in a seemingly calm manner, referring to the Fjord1 ferry shown in the scenery footage. The phrase became a internet meme, and was ranked tenth in Yahoo! Japan's keyword search ranking for the week of September 17 to September 23, 2007. Also, 0verflow decided to name its booth "Nice boat." for the Comiket 73 in December 2007, selling "Nice boat" merchandise along with its normal line of specialty items.
Along with the boat in the last scene, = epic coincidence meme.
You can imagine how much it gets drilled simply due to one of the factors, let alone all of them.
