Visible crew/equipment: You can see just the tip of the boom mic on top of the frame for 5 seconds, before Dr. Lee tells Turk that he passed the Cooper's ligament three times.

Continuity: The heart monitor lines change a few times, from being close to the neck going straight back, to going around the right side of the pillow.

Revealing: When the old lady patient is seen "escaping" she lifts the walking frame up out of the hole and it catches the set and lifts it into shot.

Continuity: When J.D. picks up the granddaughter to blow out the candles on the cake, there are 3 candles placed at the front of the cake in the camera close up, but there weren't any before he picked her up.

Continuity: When JD is at the birthday party, watch the chocolate on his face. At one point there are two separate bits of chocolate on his left cheek, then the shot changes and they are gone. The shot changes again and they are back.

Revealing: Just before all the bricks fall on JD and it's a surprise, you can see him flinch before they hit him.
