Continuity mistake: When Bulldog is talking to Frasier in the booth at KACL, in one shot his left sleeve is pushed up his arm and his right sleeve is down to his wrist. In the next shot it's just the opposite - his right is pushed up and the left is down. At the end of the scene both sleeves are pulled up.
Continuity mistake: In the scene where Frasier and Niles are talking in Cafe Nervosa, the position of Niles hands and arms change a couple of times. At one point, while Frasier talks about the young woman he has met, Niles folds his arms in front of him but in the next shot to Frasier, we can see Niles fingers laced together - and then the shot returns to Niles with folded arms. They stay this way until another shot where he says "You were in a mall?" and his hands are suddenly on the table and one is lying over the other.
