The song at the end of the video about The Hobbit: An Unexpected Journey that asks viewers to subscribe, encourages them to watch other videos, and warns against feeding the trolls.
Let's face it, even after all those years the "Terminator meets Back to the Future" Fake Trailer is still the most awesome video they made. Watch it on the Youtube and at any given time among the ten most recent comments will be pleas to expand it into a full movie. The video doesn't even have that many jokes, it's just So Cool It's Awesome.
Thor delivers a pretty sick burn to Superman and Batman in his HISHE:
That may be true... but at least I have a father.
To the point where both Batman and Superman admit it was sick.
Captain America pulls one off too when he points out that the Justice League movie's still in Development Hell, while the Avengers (At the time of the video) were gearing up for their venture. Even Batman and Superman admit that's a pretty good burn.
And to top it off, we have the Avengers et all reminding Sups and Bats about their box office income.
The DC duo gets back at one of them, by leaving Thor in the booth while they hide outside.
The HISHE guys even managed to get an MOA in a video that wasn't even theirs at the end of The Nostalgia Critic's Man of Steel episode, happening to be in the same restaurant as NC's version of Batman and Superman, after it's noted that the scene seemed familiar. And of course HISHE Batman's response to NC's Batman:
In how God of War should have ended, Kratos goes berserk and decides to kill every god. However, he is unable to kill Morgan Freeman, because he is just that cool.
After their take on both Lord of the Rings and The Hobbit had the "use the eagles to solve everything" joke, How The Desolation of Smaug should have ended defies it instead, with Bilbo chewing out Gandalf for trying to use it a third time.
