Arthur “Turkey” Gehrke of Watertown, Wis., had an odd habit. Every November he would go to bed and stay there until the following April. He told the press, “I hibernate and don’t get into trouble; while I may miss some fun, I also miss a lot of disagreeable things.” He also said, “If more folks went to bed all winter, there wouldn’t be so much trouble and confusion in the world.”
Strangely, his business didn’t suffer because of his sleep habits. He owned a bar, the Turkey’s Roost. He hired a temporary bartender to replace him during his hibernation, and the publicity because of his hibernating actually attracted extra business.
Gehrke began his habit of hibernating in 1913 and continued it until his death in 1942.
