Boo! Humbug - S1-E5

Continuity mistake: As Jack is trying to open the massage table, Karen is sitting waiting: on the small table next to her is a candle. The candle alternates from lit / unlit between a few shots. (00:07:20)
The Truth About Will & Dogs - S1-E10
Continuity mistake: Grace asks Will to watch the dog quickly as she goes to the bathroom. As she puts the dog on the sofa, the position of the wine bottle, wine glasses and cork on the coffee table change between shots. (00:26:40)
Continuity mistake: When Jack lets slip about Will's affair with Steven to Grace, he throws a blue tassel to the floor, and bends over so Grace can kiss his butt. But when he stands up he puts a purple tassel back on the table. (00:28:15)
Continuity mistake: As Grace and Campbell kiss on the couch, Will returns to the cabin and then Grace shuts Campbell outside. The edge of a rug with tassels is sometimes draped over the back of the couch in some shots, and isn't there in others. (00:15:25)
The Unsinkable Mommy Adler - S1-E13

Continuity mistake: After letting Campbell out, Grace pulls the white blind down the door, and it stops about halfway down the door, and gets stuck, and is still rolled at the bottom. In the very next shot, the white blind is now unrolled all the way down perfectly. (00:07:00)
The Truth About Will & Dogs - S1-E10

Will on Ice - S1-E11
