Brock Samson had previously broken out the passenger's side window of his Dodge Charger but in the final scene of the episode, when the car is acting autonomously (al-a Christine), the window is intact.
Brock refers to the cylinder as a gramophone cylinder but gramophones used disks, not cylinders.
The area where Hank is digging has no windows which would indicate a basement room, yet Brock's room is just inside where the digging is taking place - with windows.
Early in the episode, White tells Billy that the solution to the Rusty Venture cartoon riddle is a URL. Billy says this is impossible, since the show was made in the 1970s. Later on while trying to solve more of the riddle, White tells him, "the poor chump who came up with this riddle didn't bank on us having the Internet."
