"Each episode is typically based on a statement which sets the goal of the competition in a "who is...?" or "who can...?" style; occasionally a "first one to... loses" statement is used instead. Competitions sometimes take the familiar form of performing a task the best, such as catching the largest fish; but they are more often unusual tasks, such as who can be tied to a goat the longest. The other typical style of competition is endurance to see who can do or abstain from something the longest."
Some of my favorites episodes are:
Who can wear a dead octopus on their head the longest.
Who can remain homeless the longest.
Who can go the longest without speaking or ...sleeping.
Who can stand the longest.
Who can dance or ...sing the longest.
Who can eat the most meat.
All of the episodes are available on You Tube. I highly suggest watching them.
