Barnard Arnold "Barney" Gumble is a recurring character in the American animated TV series The Simpsons. He is voiced by Dan Castellaneta and first appeared in the series premiere episode "Simpsons Roasting on an Open Fire".
Barney is the town drunk of Springfield and one of Homer Simpson's friends. His loud belches and desperation for alcohol serve as frequent sources of humor on the show, though Barney sobered up in the Season 11 episode "Days of Wine and D'oh'ses" before relapsing three years later. Barney was inspired by the cartoon character Barney Rubble from The Flintstones and by several barflies from other television programs. In 2004, Castellaneta won an Emmy Award for voicing various characters, including Barney.
Barney can be seen in The Simpsons opening credits since 2009, passed out under a pile of leaves (but still holding his beloved bottle of Duff Beer) and being awoken by Bart Simpson skateboarding over his stomach, causing him to let out his trademark belch.
