What a coincidence. The world's best selling single malt showed up in what is arguably the best television show of all time. Anyone who has watched The Wire from beginning to end knows that this series sucks you in unlike any other. Each scene is like a domino which falls one after another toward an inevitable spectacular conclusion.
There is a Jameson appearance in nearly every episode but it wasn't until the 2nd last episode of the series that we are treated with a single malt scotch appearance. The scene which features the Glenfiddich takes place at the 24 minute mark of the 9th episode of season 5 entitled "Late Editions".
