The episode was directed by Chris Clements and written by Daniel Furlong and Zach Posner.
Homer saves it one more time, only to break his beer mug, go berserk and smash the violin.
Moe receives a phone call, rages at the caller, and angrily chases the customers out of the bar.
Marge and Homer attempt to reunite the family by inviting Moe, his brother Marv, his sister Minnie, and his father over for dinner.
At dinner, things are tense between Moe and his family members, so Marge and Homer bring a television into the dining room to show the Szyslayks the good times they had together.
Marv and Minnie retaliate by controlling the up and down button outside of the store, constantly torturing Hans Moleman as he is trying out a mattress.
Furlong reached out of fellow Oneida County native and executive producer John Frink for a job and was eventually promoted to writer's assistant on the show.
Executive producer Matt Selman had an idea for an episode about Moe and offered Furlong and his writing partner Posner the job to develop the script.
[3] The credit scene is a recreation of the Mattress Man commercial from the 2002 film Punch-Drunk Love.
