Aww man, with a title like "Mongolian Death Worm" I was expecting some hella heavy throat singing metal band.
Anyways, if an investigative special starts with rhetorical questions "Could a deadly worm be lurking in Mongolia?", "Could aliens have visited this couple?", "Are these events a message from beyond?" the answer is always "No."
So I'm pretty sure the cliffhanger is "it's not a death worm".
What are you talkin' about man? Plenty happens on Ghost Hunters! All those "cold spots" they're always feeling in rooms, all those times they thought they heard something that sounded like maybe somebody talking, kind of...
The Pitch: Each episode features five to ten minutes on some obscure cryptozoology subject which the crew will "search" for, and the rest of the program will be devoted to the central personality making jokes at the locals' expense, eating things that aren't appetizing such as spiders (it works for Bear Grylls after all), and sightseeing.
You could condense every episode down to ten minutes tops but there'd still be no results.
