From the Discovery Channel's description of the Dagorhir segment:
Dagorhir (which translates to "battle lords" in author J.R.R. Tolkien's Sindarin Elven language) is both a sport and a game that combines fast-paced, full-contact combat simulation with elements of live-action role-playing. Dagorhir battle games combine elements of both history and fantasy, allowing participants a wide range of character choice.
The segment is one of six which also include:
- Lawnmower Racing
- Alligator Wrestling
- Chess Boxing
- Tug Fest
- Catfish Grabblin'
So far, the "Catfish Grabblin'" seems to have sparked the most interest.
