To be honest, this kind of thing has been a recurring joke on YouTube comments for quite a while now. For a really abrupt/humorous thing like this, somebody will always be there to say it's better than Twilight.
It's kinda getting old, just like making fun of Justin Bieber. I notice the balloon thing is supposed to be funny, and the point is that it's so insignificant it is still better than Twilight, but I have a few suggestions that might make it funnier.
Something that would've been much better was a buildup with the balloon. This could work with another choice of sad music. Where it's being shown leaving, and eventually floating up faster and faster.
You might misinterpret that last paragraph and think "but it's not supposed to be serious." If it's serious, then the comedic exaggeration will make it even funnier.
just some pointers
