Wow, I can hiss, too. That makes me a Reptile. There is no other explanation. I am a shapeshifter, and I can fly into the air and bite the heads off little children. But, we first must dumb down the human population first.
See, we came here in flying spaceships, but instead of blowing the fuck out of the planet, we choose to infiltrate the population in more subtle means. This way, the invasion can take 30-40 years, instead of 30-40 hours. That makes sense, doesn't it? After all, if we have the technology to go light years in space, we must have had the technology to turn the entire planet's population into a liquid goo, right? We just choose not to use it.

Robert: The subjunctive?
Rosalina: That's not the subjunctive.
Robert: I don't think the syntax has been invented yet.
Rosalina: It would have had to have had been.
Robert: Had to have...had...been? That can't be right.
