This is, hands down, my favorite TED talk of all time. That isn't hyperbole. I spent three days trying to pull out some highlights to share and ended up with a second-by-second recap of the whole dang thing.
Just hit play, and let the awesomeness wash over you (but especially pay attention around the 10-minute mark because that's when things get really good).
You should probably share this with all your friends. Especially if they're dudes. Just sayin'.
