"Old Bugs" is a short story by American horror fiction writer H. P. Lovecraft, probably written shortly before July 1919. It was first published in the Arkham House book The Shuttered Room and Other Pieces (1959)
With the onset of Prohibition, the Sheehan Billiard Room in Chicago became a sordid haunt for hard drinkers. A certain Old Bugs, a mature man corroded by vices but capable of showing, at long intervals, the typical sensitivity of educated people works as a kitchen cleaner. When the young Alfred Trever, initiated by his friend Pete Schultz on the way of drinking, arrives at the Sheehan's tavern, Old Bugs will try to convince him not to make the same mistake as he did.
