It's funny that we were inclined to click on the link. We never cook lobster, but part of the reason is fear: Fear of handling live things with big claws, fear of them suffering while boiling to death, etc.
And this video isn't promising a painless or hands-off death. As the title suggests, you're killing here. But this method appears more humane. You let the lobster hang out in the freezer for a few minutes (to numb it), and then you kill it as quickly as possible with a swift slice through the brain.

We'd recommend making sure your chef's knife is newly sharpened.
