South Park: Bigger, Longer and Uncut - Dude, I'm Psychic... Sweet!
This seems a bit weird to me: When Cartman packs his rucksack (when hes in his bedroom, just before seeing Kennys ghost the first time), he puts in it a mirror and a rope. At this point they have not met (or even heard of) The Mole. When at the USO show, The Mole asks Cartman "Did you bring the mirror, and the rope....". Now how did Cartman know he would want those things before even meeting the guy?!
