The big time - S3-E8
Continuity mistake: While in bed with Aidan Carrie's left arm position has no continuity between shots, specially when she toys with his necklace with her right hand but a shot later it's the left hand.
Continuity mistake: While Charlotte has dinner with a couple, he has his arm around her shoulder, leaving no gap in between them; yet from the angle behind there is a gap.
Revealing mistake: When Sam is having sex with the doctor, you can tell she has a skin-coloured bra to stop her breasts from being shown.
Continuity mistake: When Charlotte is talking during breakfast her left arm is either still on the table or moving.
Continuity mistake: When the breakfast scene starts, Sam is either drinking from a straw or holding her drink away, between shots.
Continuity mistake: After spilling the sauce on the floor, when Miranda is discussing with her boyfriend her bag suddenly disappears from her shoulder. Later on it magically appears on the floor.
Continuity mistake: When Miranda drops the paper bags on the floor a lettuce and a bottle of water fall out. Seconds later the stuff changes completely: The bottle is gone, the bags are in a different position and, best of all, Miranda's leather bag (which was previously hanging on her shoulder and suddenly disappeared between shots -listed mistake-) magically reappears on top of the mess.
Continuity mistake: When the tomato jar crashes on the floor, the splatter changes shapes between shots and the label disappears in the second shot.
Continuity mistake: Baird puts a sock inside Charlotte's crotch and her tie gets skewed. A shot later it's straight.

Visible crew/equipment: When Stanford and Carrie arrive at the furniture place he says "look at this place." Check the reflection on the shop window: There's a boom mic following them.
