Continuity mistake: During the episode when Claire and Phil do their warm-up before racing each other, their children Alex and Luke arrive from school. They get down from the car, and the car takes off and goes away. But in the 2nd shot we can see that same car parked in front of them. (00:17:00)

Boys' Night - S2-E18
Other mistake: In the opening scene, the Dunphys are playing ball in their backyard when Claire knocks it into their crotchety old neighbour's yard. They all head in, and as Phil explains to Luke that it's because it's their only ball, another ball is in the grass visible over Luke's shoulder.

Haley's 21st Birthday - S6-E10
Plot hole: The family mistakenly believes Hayley will be having her first drink. However, there were several instances in earlier episodes where they saw her drinking or drunk, or she admitted she'd been drinking. For example, in the episode "Arrested", the family drove down to bail her out of jail for underage drinking, and they saw the video footage, and the family members who didn't go were informed of the situation.

Phil on Wire - S3-E3
Other mistake: When Cameron follows Mitchell into the sea, Cameron's shirt is visibly wet even though he is in a very shallow area of water. After cutting back to Cameron, the wet mark on his shirt has gotten bigger and traveled further up his shirt even though there are no significantly large waves that could have caused him to become so wet.
Continuity mistake: Pepper states in this episode that he doesn't have any kids, but in 4-14 "A Slight at the Opera" he talks about a son he has who is a Navy Seal.
Continuity mistake: In the scene before Jay hits Phil in the face with the plane, the remote control's antenna (the one he is using to fly the plane) switches between the 'forward' and 'up' positions. (00:10:50)
Visible crew/equipment: When Manny holds up the Phantom mask to Jay's face and realises it's for the wrong side, as Manny rushes back upstairs for a lefty, the reflections of the Steadicam operator and crew are visible on the minivan's surface, beside Gloria. (00:14:40)
Visible crew/equipment: When Haley walks into the kitchen she tells Dylan they're over and hangs up on him. Then when Haley's cell rings, as the camera quickly pans around, the pink T-mark becomes visible on the floor behind Haley. (00:04:35)
Continuity mistake: Mitch and Cam are eating breakfast and Cam only fills Mitch's wine glass. As the camera view goes back and forth a few times it keeps switching to show Cam's glass full then empty and so on. (00:08:30 - 00:09:30)
Continuity mistake: Claire takes some cookies out of the oven and puts them on a cooling rack. When Manny asks her what the matter is with Claire, she holds still while she's about to put down the second cookie in the top row. When the camera cuts to a different angle there are suddenly three cookies in the row already. (00:12:05)
Continuity mistake: When Phil tries to get his bike down he falls over. A lot of stuff falls from the shelves behind him, when Claire asks if he is okay and Phil answers "Yes I am" you see that the shelves behind him are a mess. But the next shot you see that all the stuff is cleaned up again. In the next few shots the background changes all the time. (00:01:00)
Answer: He has seen himself dancing, and is mortified at how bad he looks.
