Empty Whisky Bottle (Fallout 3)

The empty whiskey bottle, or "empty whisky bottle" [sic], is a miscellaneous item in Fallout 3 and Fallout: New Vegas.

Characteristics
An empty whiskey bottle is simply what the name suggests: a bottle of whiskey which has been drunk or otherwise emptied.

Within Fallout 3 empty whiskey bottles serve no appreciable purpose, with the exception of being used as Rock-It Launcher ammunition. Their low weight-to-value ratio make them impractical for being sold for profit.

Fallout: New Vegas also provides no definitive use for empty whiskey bottles within the standard game. However, the Honest Hearts add-on incorporates empty whiskey bottles as an ingredient used in crafting wasteland tequila.

Locations
Numerous empty whiskey bottles can be found throughout the Capital Wasteland and Mojave Wasteland, appearing in virtually all major areas of both games, either in-world or located inside containers. Additionally, vendors may sell the item, though none are specifically guaranteed to have any in stock.
 * Dukov's Place has an excessive amount of these, mostly on the Pool table.

Fallout: New Vegas
A total of 744 bottles can be found in the world, not counting items found inside containers, sold by vendors, or held by non-player characters. While it is impractical to list every location they appear, the following is a list of areas with a high number of empty whiskey bottles:
