What is an "Old-Fashioned"?

Watching TV Land (like the old fuddy-duddy I am), I heard one of Beaver’s friends say “I’ll have an Old-Fashioned”, but he didn’t know what it meant. Neither do I. Might it refer to Old Grand-dad whiskey?

So, what’s an old-fashioned, and what’s so old-fashioned about it? I’m not much of a drinker, obviously…
