When You Get Back to Mars, Are You Going to Get It - S3-E24
Visible crew/equipment: When Tim and Martin are carrying Andromeda to the bedroom and Martin opens the door with his Martian finger, the crewmember actually opening the door can be seen on the hinged side of the door. The crewmember continues to move in that space for about 3 seconds during the scene. (00:10:00)
Visible crew/equipment: After Graig returns Patty's math book, Cathy tries to use the pamphlet's rules as she follows Craig. When Craig thanks Cathy for helping him with Latin, the boom mic repeatedly pops up into view in the bottom right corner of the screen. (00:18:10)
Visible crew/equipment: Backstage before the dog play, after Betty Jo says, "I wish Mr. Kroger had never left him that $200," their dog, Dog, barks and enters. Three things occur in this shot: we see the shadows of the camera/mic move across the floor, a chalk mark becomes visible on the floor (where Billie Jo will soon stand), and we hear someone say, "Higgins," which is Dog's real name.
