MythBusters/Nightmare Fuel

• The Meatman is pretty disturbing in itself, but the test it's used for-- showing that a person could be crushed in a closed-dress diving suit by deep water pressure-- will haunt you for a good while. Watch... if you dare.
• Torture:
  • The standout was the Bamboo Torture Myth.
  • The Chinese Water Torture myth is this as well. Seeing Kari break down like that was brutal. Made worse because we all knew she was with friends who would get her out of there the moment she made the slightest noise. Imagine if it were real, and the people surrounding her didn't give a withered crap about her?
• The high-speed camera also counts, particularly when showing anything biological.
• There are two words guaranteed to make long-time fans cringe: "Chicken Hand".
• Also smashing quick-frozen heads to see if they would shatter like glass (as shown in Friday the 13th (film)). They brought out their trusty ballistics gel again, used a similar substance for brains...and used actual human skulls. Then for even more added realism, they used pigs' heads.
• Jamie at least had difficulty sleeping the night after they tested the escape methods from a sinking car, noting that it was like watching someone drown right in front of him.
• Likewise, Jamie's time being buried alive...and the coffin started buckling.
