Stonehenge is one of the most iconic structures in the world. People have speculated about its purpose for centuries, associating the structure with everyone from King Arthur's magician, Merlin, to the druids and the sun god Apollo. Now faux rockstar Nigel Tufnel — portrayed by actor Christopher Guest from the landmark cult comedy "This is Spinal Tap" — lends his offlandish, side-splitting opinions on who created Stonehenge, and why, in an exclusive online interview with National Geographic Channel (NGC).

Claiming he knows the name of the single man responsible for the construction of Stonehenge, Tufnel sits down with a journalist to answer some hard-hitting questions and takes viewers on an exclusive tour of his garage, where he conducts "decoder" experiments to provide evidence for the true purpose of Stonehenge.

Beginning on Wednesday, May 21, the spoof interviews can be found online at StonehengeDecoded.com and on various websites around the Internet. The viral spots are intended to drive awareness for NGC's upcoming show "Stonehenge Decoded", which presents an exclusive look at groundbreaking evidence that places this ancient monument at the center of one of the largest prehistoric religious complexes in the world. Premiering Sunday, June 1, 2008, at 9:00 p.m. ET/PT, "Stonehenge Decoded" details the first proof of a 4,500-year-old Stone Age settlement just a few miles from Stonehenge, with a mysterious near-replica of Stonehenge made of wood at its center.


Best known for his ensemble mockumentaries, including "Waiting for Guffman", and "Best in Show", Guest wrote the script and starred in the cult classic "This is Spinal Tap" in 1984.
