Visible crew/equipment: At the end, Debra walks into the kitchen and is followed by a boom mic. (00:18:40)
Visible crew/equipment: Robert walks in the back door and a stage light is visible in the top right hand corner. (00:20:20)
Other mistake: At the end in the kitchen there are a few camera angles that features a black object hanging into shot. This item moves perfectly with the camera and so is not part of the set or a boom mic. Perhaps something was dangling in front of the lens during filming. (00:20:45)

Revealing mistake: At the end, as Ray's parents walk out the back door, Robert says "extra credit". Look out the door when he says this, and you can see the house in the distance wave as if it were a painting.
Continuity mistake: Ray offers to rub Debra's feet instead of doing another chore. He takes her black socks off and throws them on the floor, under the table. The socks can be seen for a few shots, in the same spot, after Robert comes in. At one point, however, one of Debra's black socks can be seen on the couch in the middle, and in the next shot, the sock has been removed.
Revealing mistake: When Raymond runs out of The Shower at the beginning of the episode, you can see that he's wearing nude colored shorts.

Continuity mistake: When Angela says she drinks 8 glasses of water a day her hand goes from on her notepad to on her hip instantly. (00:02:30)
Revealing mistake: When we see Angela taking Ray and Bernie's order for the first time, look closely and you will see that she's not actually writing on her note pad. She's just moving the pencil up and down. (00:02:45)
Continuity mistake: When Bernie compares Angelina to the girl on the mudflaps, Ray has his knife and fork in hand which disappears in the next shot. (00:03:45)
Continuity mistake: When Debra is chopping the tomato she has 1 half left on the chopping board. Camera cuts and she is cutting another piece. (00:06:30)

Continuity mistake: When Debra is holding the cream Marie gave her she has it in two hands followed by one after an instant cut. (00:13:10)
Visible crew/equipment: Marie takes Robert's cream and says it's for Debra. When she does, two stage lights are visible above the cooker. (00:14:00)
