Other mistake: At the very beginning of the episode, Fletcher wakes up in bed and his hair is perfectly combed.
Wendy House - S3-E2
Other mistake: When Frank, Betty and the insurance assessor are sitting on the sofa, it's obvious that all three actors are trying hard not to laugh when the assessor starts sinking into the sofa.
Beyond the Farthest Star - S1-E1
Other mistake: When showing Scotty on the bridge, some of the frames show more of his body than others. In those frames, you can see that he lacks legs.
Other mistake: S48 E82: Adam calls 911 for an ambulance for Chase that has been shot, but Adam never gave the address or location where the ambulance should go. It shows up to the right place anyway. (00:05:52)
Other mistake: At the beginning of the episode, there are a few sequences with police cars going at notable speed down the streets of New York. In a few instances, you can see people gathered in street corners, looking at the filming. One egregious example is when the criminals loading the van are startled by the sirens. In the following shot, two bystanders look at the car, then turn towards the camera, and one even takes a few steps back to get out of frame. (00:03:40)
