A Classic Old Fashioned Bourbon Cocktail (or Rye in a Pinch as Don Draper Would Say)

Drinks don't get any better than this! For a classic old fashioned bourbon cocktail, place a sugar cube in a glass and either leave it solid or muddle it (crush it with a muddler or a spoon), then add a shot of bourbon (or Rye in a pinch as Don Draper would say -- see Mad Men season three episode three), two or three dashes of bitters, a splash of water, and some orange peel (or a slice of orange if preferred).  

Bitters make things better.
