king of queens ran for nine seasons. By all accounts, the show was a success, and it still holds sway today. Available to stream on Peacock, there has been renewed interest in the classic series. However, watching episodes in rapid succession makes glaring errors a bit more obvious. With each binge-watch, a new continuity error is discovered. We collected the king of queens three most glaring continuity errors for your consideration.

Spence ate peanut M&Ms before revealing he had a peanut allergy
A peanut allergy is no laughing matter. Apparently, Doug Heffernan’s best friend, Spence Olchin, had such a severe peanut allergy that it required a hospital visit. Spence’s fragile health and allergies have been a story more than once on king of queensand his peanut allergy was widely discussed in later seasons.
Peanut allergy is a serious king of queens continuity error, however. In a Season 1 episode, Spence is seen eating peanut M&Ms at the Heffernans without having an adverse reaction. It seems unlikely that Spence developed a life-threatening allergy later in the series that was never mentioned. So either Spence was faking his allergy or the writers forgot he was enjoying the beloved yellow bag of M&Ms in Season 1.
The Heffernans’ neighbors ripped them off then came back as if nothing had happened
Tim and Dorothy Sacksy appeared in season 1 and season 2 of king of queens like the annoying neighbors of the Heffernen. In Season 2, things speed up when Tim convinces Doug to invest in a pyramid scheme involving water. After convincing Doug to participate in the scam, the couple disappears.
If Tim and Dorothy had stayed away, we wouldn’t have had any problems with the script. They didn’t stay away, however. Instead, the couple returns in Season 3 of king of queens Like nothing ever happened. Doug never mentions the pyramid scheme, nor the couple. fans of king of queens find this particular continuity error infuriating as it could have been a fun story.
Carrie’s half-sister was never brought up after the show’s first season
When king of queens aired its pilot episode, Arthur Spooner’s house burned down and moved him. That’s how he came to live with Carrie and Doug. The setup was a creative way to have Carrie’s aging dad move into the couple’s basement, but the show’s original writers added an additional complication. Arthur wasn’t the only member of the Spooner family to be displaced by the fire. Carrie’s sister Sara has moved into the couple’s guest room.
Sara Spooner meant a lot in the first handful of episodes, then she disappeared completely. According to Fandom, Kevin James once revealed that Sara was cut from the show because the show’s writers didn’t know how to fit her into the family dynamic. It’s understandable, but several storylines made Carrie feel like an only child. Whether the budding actor moved away or ran away with a new love would have made more sense. His sudden and unexplained disappearance is one of the most obvious king of queens continuity errors. She wasn’t the only character to randomly disappear, however.
