Squatty Probst

Squatty Probst is a recurring endurance challenge that debuted in and later reappeared in.

Rules
Castaways must stand in a squatting position, releasing the safety from their apparatus holding up an urn of water above a fire. Should they stand too high, their urn will spill, extinguishing their fire. If they go too low, a flag will release, eliminating them from the challenge. The last castaway standing wins.
