The show How It's Made always provides an interesting look into how products we use every day come into being. How is a marble made? What about saxophones? Is my neighbor always watching me especially at night? That last one is actually a pitch for the show. They should do an episode on that because I'd love to know.
The episode featured in the clip below takes us inside the Patron Tequila distillery for a look at how the thing I had for breakfast and lunch today gets made. However, towards the end of the show the learning is derailed by the appearance of the Master Distiller and his distracting hairpiece.
