I saw an episode of Fear Factor that made my hair stand on end. They had two perspex boxes with elasticated T-shirt neck openings at the bottom. These boxes were side by side and shared a common division in the middle. On the inside of Box 1 was a keyrack with 4 keys, and there was a small opening in the perspex divider between the two boxes.
Okay, two boxes, one with keys, both obviously designed to have the contestants poke their heads through the T-shirts so that there was a head in each box. The object of the exercise was for person A to remove each key from the rack in Box A, using his mouth only, and then transfer it to the opening in the divider, where person B would receive the key and then spit it down a glass funnel in the front of Box B, where the key would appear in Person B's hands waiting underneath. All this to unlock 4 locks in the fastest time (it was a paired contestant game).
But hang on....haven't I missed something?
Ja.
The shed-loads of assorted tarantulas and other spiders that were in the boxes!!
At one point, Person A couldn't get at one of the keys without getting a spider in his mouth, and his sister (Person B) was squealing no-end because one of those pink-kneed tarantulas was on her head :-o
