Theodore Roosevelt was America's 26th president, after raising cattle in North Dakota, fighting in the Spanish-American War, and serving as governor of New York, among other adventures. Many legendary but true tales are told about Teddy, including the one in which the Teddy bear was named for him. But there are always more. I have written about Roosevelt several times, and one even I hadn't heard of happened sometime around 1884.
Roosevelt entered a bar in Montana and saw that one guy was so drunk he had already shot the clock on the wall three times. Holding two guns, he mocked Roosevelt for wearing glasses and ordered him to fix drinks. Roosevelt managed to convince the drunk fellow that he was no danger, then punched him good, knocking the guy unconscious to the cheers of everyone in the saloon. The drunk left town and never came back. When Roosevelt told the story in his autobiography, he included a lot more details. You can read that one and five other true stories that show just how fearless Roosevelt was, at Cracked.
