The Gang Solves Global Warming - S14-E10
Factual error: When Charlie and Dee go to get ice, they go to a "liquor" store, down the road. In Pennsylvania, all liquor stores are state run, called "Fine Wine and Spirits", and only sell liquor and wine. In this scene, ads for liquor, beer, and wine are all on the outside of the business. Liquor stores in PA do not sell beer.
