Call me crazy, but Dave's Insanity is definitely not as hot as it gets, at least where I'm concerned. I collect hot sauces, and I take them seriously.
Staying safe where kids and friends are concerned is always a priority, though. Anyone that knows me, knows that I'm not the one they ask, to see if something is "hot". I'm a true nut, when it comes to heat, but pranks like the one you linked to are out of the question. They happen all too often, just like kids who try to eat ground cinnamon, on a dare.
Serious scoville units are definitely cause for caution, even for someone who has an addiction.
Play like you've worked at it, and don't worry about sounding like your influences. You can't cheat on them, or your practice, anyway. If you've worked hard at your skill, your audience will know it.
