George Thorogood walks up to the bar: One bourbon, one scotch, and one beer
Bartender: sighs OK, man, we got Macallan, Dewar's, Johnnie Walker, Bowman, Glenfiddich, Ardbeg... We got Miller, Bud, Blue Moon, Fat Tire, uhh, Flying Dog, and a bunch of cans and bottles... Look, can you be a little more specific? I got other customers.
