Gus Duncz

Gus is a loud, elderly diner owner who also happens to be Andy's neighbor. He gets angry quite easily but despite that, he doesn't seem to be a terribly violent person, just a guy who yells a lot. He was voiced by Nick Jameson.

History
A gay man in his late 60s, he owns a diner in Mission Hill. He is a very large, burly man with a short temper and is married to Wally.

According to audio commentary by the producers, Gus is based on Broderick Crawford, though according to the audio commentary for the season seven Simpsons episode, "Marge Be Not Proud," Bill Oakley and Josh Weinstein claim the inspiration for the character was Lawrence Tierney (who voiced the Try-N-Save store detective who catches Bart shoplifting).
