More snake oil:

- Bottled water. Holy cow. You melted a glacier for this?

- Vodka. Really. It's just pure ethanol diluted with water, unless the distillery was cheap, which means you also get methanol and other poisonous loveliness.

I believe "snake oil" had its genesis in "patent medicines" which had all sorts of quackery (and/or opiates or cocaine) about them. The modern derivatives of that world, such as Italian amari, are at least quite tasty.
