As JIM LEHRER has admitted on "The Colbert Report," it takes a lot of courage to be boring on television five nights a week. But under the placid PBS façade lies a man with real heart. Lehrer visits Decatur Library to discuss the latest of his 19 novels. Set during World War II, Oh, Johnny tells the story of Johnny the baseball player, Johnny the boy in love and Johnny the flamethrower operator on the suicide squad in Peleliu, Palau. Free. 7:15 p.m. 215 Sycamore St., Decatur. 404-370-3070. www.georgiacenterforthebook.org.
