Peter Boyle claims that he was aided in getting the part of Frank Barone by events prior to his audition in New York City. He had gotten lost and couldn't find the location of the audition, so when he showed up, he was agitated and sarcastic.
The three Barone children (Ally, Geoffrey and Michael) are actually siblings in real life (Madylin, Sawyer and Sullivan Sweeten respectively). Nineteen year old Sawyer Sweeten sadly ended his life on April 23, 2015.
Each episode ends with a plate of food (never the same two dishes) being offered to the viewer. After the show's final episode, instead of food a check with "no charge" on it was set in place of the plate.
In Season 2 episode 6, it is Frank and Marie's 40th wedding anniversary. In this episode it is revealed that Robert is 4 years older than Ray. In episode 10 of the same season, it is Ray's 20 year high school reunion. This means Raymond is around 38 in this season, which mean Robert is 42. This means that Robert was born 2 years before Frank and Marie got married.
Throughout the series when Ray comes home he calls Debra a different nickname. All of these were improvised by Ray Romano. Sometimes he would have to come up with as many as fifteen names depending on how many takes were required.
Patricia Heaton's father, Chuck Heaton, is a retired sportswriter - Ray Barone's profession - for the Cleveland Plain Dealer. He was mentioned in one episode, where Ray was up for an award against a writer named Chuck Heaton. In the episode, Debra offers up a 'Bronx cheer' when her real-life father's name is mentioned.
Kevin James acted 8 times in Everybody Loves Raymond (1996). In his first six appearances, during seasons one and two, his role name was "Kevin Daniels". In the final 2 appearances, during season three, he portrayed his "Doug Heffernan" character role from The King of Queens (1998). This is probably because the final appearance as "Kevin" took place in May 18th 1998, while The King of Queens (1998) did not debut until September 21st, 1998.
