I lived on Gibraltar island last summer. I was there when they filmed that show. After the last day of filming, we all went to a few bars on PIB with Mike Rowe and his camera crew. Mike is a nice guy.
He has interesting name. Few people called him microscope, microchip, Microcystis... If you listen closely in first minute, Kristen is telling him that they were going to catch snakes, take them back to the lab and insert a microchip in them. Immediately after Kristen says the word microchip, Mike replies "a mike rowe."
