Fred Astaire & Ginger Chicken - S6-E20
Plot hole: Jack spends part of this episode clumsily teaching Karen basic steps of the fox trot for her wedding dance with Finster. However, in season 4, episode 16 ("A Chorus Lie") It is established that Karen and her husband Stan have, for years, performed an annual spotlight dance at their Valentine's party on Shelter Island. Later, she and Will are seen beginning a rather elegant fox trot to "Someone to Watch Over Me," complete with spins and a dip.
Continuity mistake: When Grace and Karen enter the cabin, Grace puts her bag down on top of the sofa, so that the large bottom faces the door. In the next shot when she walks back over the bag has now changed position so that the bottom of the bag faces us. (00:04:50)
Continuity mistake: When Dr. Hershberg is crying after giving some bad news, he knocks a grey box off of the small equipment table which he is leaning on. Later during the scene the box suddenly jumps back up onto the table. Also, the other items on the table jump around and change position on their own accord a few times. (00:05:00 - 00:07:00)
Home Court Disadvantage - S6-E3
Continuity mistake: When Grace is getting Leo to tell Karen the joke to her in her office, in some shots we see a very long roll of white paper across her desk. But in some side shots, it isn't there. (00:11:10 - 00:13:40)
A Gay/December Romance - S6-E12
Continuity mistake: After Grace drops her take-out container of Happy Noodles, in the restaurant, the position of the container on the floor changes between shots from laying down to on it's side. (00:06:20)
Continuity mistake: After Dr. Hershberg makes the joke about the small cup of urine, he places it down on the side by the small equipment table, yet in later shots you can see the cup on the side by the door. (00:06:00 - 00:08:20)
Character mistake: When talking to Will on the phone, Grace misuses the term "pied-à-terre" (which means "apartment" in French) instead of "pas de deux" (a dance for two) while describing the delicate and complex nature of a relationship between two gay men. When Will points out her error, she says she knows what pied-à-terre means because she took Spanish in high school. However, in season 1, episode 20 ("Saving Grace"), Grace correctly and easily used the term pied-à-terre while showing her sample book to a potential client.
Other mistake: During the court hearing the cop Vince mentions looking in the trunk of Karen's car. Nowhere in the scene prior when he stopped them did he look in the trunk.
