Petey: Captain, I'm very concerned.
Tagon: What's the matter?
Petey: I selected the most topologically remote site on the entire planet for our team's landing. They proceeded to land right on top of an ancient race of aliens who know schlock's entire life history.
Tagon: Wow, what are the odds of that happening?
Petey: This is the grave-world of an ancient civilization. I say the whole planet must be haunted, and this is proof.
Tagon: You don't still have a ghost-phobia, do you?
Petey: We could destroy the planet and pretend we were never here.
