Don't Eat the Snow in Hawaii - S1-E1
Factual error: Magnum manages to lure the dogs outside making them wail in pain as he plays a sound that greatly bothers them. As great and sensitive as dog hearing is, Magnum put in the sand past the perimeter wall of the mansion a little Sony Micro cassette recorder M-202 and played the sound off its in-built speaker. That would hardly produce, especially at that distance, an output worth the kind of reaction displayed here.
