The phony Bear Grylls faked it in Kilauea Volcano. He taped most of the show a few hundred feet from the highway. I have hiked this area hundreds of times and shot the second half of this clip myself. Just watch!
Circa 1992, Mike Rowe (host of Dirty Jobs) worked in (very) late-night TV selling crap to idiots on QVC. He used the opportunity to its full comedic potential.
