'Moe' Lester Szyslak
Voiced by: Hank Azaria
Owner of a seedy dive he optimistically calls a tavern, Moe is the loathsome and repulsively selfish bartender catering to Springfield's drunks. Homer is regularly seen at the bar, as are Bart's infallible prank phone calls.
Barney Gumble
Voiced by: Dan Castellaneta
Named to match Fred Flintstone's best friend Barney Rubble, Barney and his loud belch provide a valuable insight into Springfield's beery underbelly. When sober, however, he is not just a skilful man of many talents, but also a wonderful tenor singer. Sobriety however comes below turpentine on the committed drunk's priority list. He keeps Moe's Tavern alive.
