Better Never Than Late - S3-E16
Visible crew/equipment: While Kate and the family are seated on the Cannonball headed to Pixley, after Charley tells Floyd to look at the pressure gauge (because he forgot to load the tender), when it cuts back to Kate we can see a crew member (animal trainer likely) making hand gestures, at the right side of the screen.
Visible crew/equipment: When Uncle Joe shows up at the delivery entrance to the Pixley Hotel, the shadow of the boom mic swings into view at the left side of the screen.
Visible crew/equipment: With fifteen minutes left before the bomb goes off, it then cuts to the Shady Rest. When Kate says, "It's as clean as I've ever seen it," the actor's white tape mark is visible on the carpet, as Uncle Joe heads to the couch to take a nap.
Spur Line to Shady Rest - S1-E1
Visible crew/equipment: After Bedloe thinks he's fired Sam, he exclaims, "Well, if this isn't the nuttiest," and when it cuts to Charley and Floyd helping the Bradleys, there are three chalk T-marks visible on the ground.
