A man walks into a bar, asks the bartender for a glass of water. The bartender pulls out a shotgun, and fires a round nearly missing the man’s ear. The man says thanks, and leaves a tip. Why the water, why the tip?

The man's unusual thank you and tip to the bartender, who responded to a request for water with a loud shotgun blast, makes sense when considering a common, involuntary bodily function: hiccups. Rather than being a hostile (Review) act, the bartender's extreme measure was likely an attempt to cure the man of a persistent bout of these bothersome spasms.

Hiccups, medically known as singultus, are involuntary contractions of the diaphragm, the muscle that separates the chest from the abdomen and plays a crucial role in breathing. Each contraction is followed by a sudden closure of the vocal cords, producing the characteristic "hic" sound. They can be triggered by various factors, including eating or drinking too quickly, consuming carbonated beverages or alcohol, excitement, or emotional stress. While usually harmless and short-lived, they can be quite uncomfortable.

Many traditional remedies for hiccups aim to either stimulate the vagus nerve or disrupt breathing patterns. These can include holding one's breath, sipping ice-cold water, or swallowing granulated sugar. A sudden shock or startling sensation, such as a loud noise, is another well-known, albeit drastic, method to stop hiccups by overwhelming the vagus nerve. In this scenario, the jarring sound of the shotgun blast served as that sudden shock, effectively interrupting the man's hiccup reflex. His gratitude and the tip were a clear indication that the bartender's unconventional "cure" had worked.
