When Jerry Musso rolls his eyes at Ray behind his back, Ray immediately notices it. This is pretty unlikely, though, given the fact that Jerry was completely facing the other way when he did it.
In the scene with Ally and Frank in the backyard, you can totally tell that Madylin Sweeten (Ally) is trying not to burst out laughing throughout the majority of the scene, namely when Frank is sitting on the picnic table and breaking it. Notice that Sweeten is looking straight ahead and doing her best to keep a straight face, but you can see she's having a hard time.
In the epilogue scene, when Robert is in the backyard talking to Ally, Marie comes out and barks at him for not taking out the garbage, and that she has to do it herself just like everything else. But you can clearly see they're in Ray and Debra's backyard, and Marie is in their house, not hers. So why would she be complaining about the garbage there?
In some shots, purple and green studio lights can be seen reflecting off of Marie's glasses.
When Ray sees Angela eat the fly, he holds the same shocked facial expression for a long period of time. Ray Romano has often said that he was left feeling lightheaded from doing that for so long. Then, when he yells to Robert and Debra, "SHE ATE IT!" look closely. He looks as if he's about to fall over and faint, and Romano attested to that in later interviews.
Albert Romano & Max Rosenthal, who play Ray's father's friends, are the fathers of the creators.
When Robert grabs the video game console, he doesn't unplug a single wire from the TV, despite the fact that he and Ray were playing games right before that.
Bernie and Linda mention their son Benjamin but never mention their daughter Madelyn (she was mentioned when Ray and Debra wanted Bernie and Linda as their children's Godparents).
In "The Wedding (2)" it is Debra who introduces Father Hubley to Ray. However in this episode, it appears Father Hubley is the family priest of the Barone family (and has been for a long time), and this time, it is Debra who is introduced to Father Hubley by Marie.
Marie says that she would never deny her kids water and Frank replies by saying that that would explain Robert's bedwetting problem. However, Robert's bedwetting problem has already been exposed as a prank perpetrated on Robert by Ray much earlier.
At the end of the episode, Ray and Debra watch from the doorway as their kids play. At one point, the twins tackle Ally to the ground, to which she says "Get off of me!" and dissolves into a fit of laughter. Then the camera points to Ray and Debra for about 15 seconds as their children continue with their roughhousing. After a while, Ray puts his arm around Debra, and just at that moment, we hear Ally yelling "Get off of me!" and laughing hysterically, the dialogue duplicated.
Ray and Robert claim that Frank never gave them the sex talk. In "The Ball", however, Ray is rather annoyed that his parents told him the truth about Santa Claus only when he was 14, because Frank wanted to cover sex and Santa at the same time.
Frank claims "Marie knows she's in the pain in the ass." In many other episodes however, Marie seems completely clueless as to what she did wrong. Of course, there is the possibility that Frank and Marie were just lying, just like Ray and Debra.
This was one of two episode submissions that won Brad Garrett his first Emmy for Everybody Loves Raymond. The other was "Raybert."
This was one of two episode submissions that won Doris Roberts her 2nd consecutive Emmy for Everybody Loves Raymond. The other was "Marie's Sculpture."
Alexandra Romano, who plays Ray's daughter Ally's best friend, is Ray Romano's daughter.
Marie mentions in this episode that Robert never attended college, but how is that possible if he is a New York cop?
The adults all dance to "Jungle Love" at the end of the episode. This is the very same music used in the opening credits for the following year, which was Season 7.
In the syndicated version, the episode starts out with an outside shot of Ray's house. But then it goes straight to a scene in Marie's kitchen.
Debra says she used to read Ray's column a lot when they were dating, even though in "The Wedding (1)", Ray used his very first column to ask Debra to marry him.
