In 2013, MythBuster Adam Savage held a Reddit AMA (Ask Me Anything) session. For some of the most frequently asked questions, he posted video replies along with his team from Tested. The most interesting is his answer to Reddit user 1Patrick's question: "Since the start of MythBusters, what is the most scariest experience you've ever had?"
Watch below for the answer, along with the killer line: "Calm people live. Tense people die." Also note that the first few seconds are black; just give it a moment.
If you want to see the moment in question, here's a clip—warning, it's pretty alarming! Including this quote: "It's pretty definitive that I died right there." -Adam Savage.
