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 review of Man of Steel, they happen 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:
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.
"The Lego HISHE" continues right from where the Movie has ended. It's made for a tiniest fraction of the movie's budget, but looks just as AWESOME!
It also sees (Lego!) Superman single-handedly take out all of Lord Business' forces and hailed a as hero, rather than get taken out by a wad of gum in the movie (which Batman suggests must have been "Kryptonite gum").
Later in the video, Superman and Batman look outside to see an epic battle being waged between the Master Builders and the Lego Duplo aliens that popped up at the end of the movie.
Duplo Alien: We are here to destroy you! Emmet: (clobbering enemy in his Mini-Mecha) No, no you're not!
In The Godzilla HISHE, Walter White has Godzilla roar right in his face and doesn't even blink! BADASS!
