"Pluto"
I feel bad for poor Pluto. He was on top of the world, until one day scientists thought they were better than him, so he has to fight his way back to the top and win the girl of his dreams with an 80s montage of him training.
Well, Pluto's still awesome.
And it would be hilarious, but very very very impossible if all of the calculations by scientists were wrong and Pluto was the only other planet with life, but it's probably not possible. It would be hilarious though.
Word of the day: nosegay (I'm not joking, that's a word. It means a small bouquet of flowers.)
