The Song Remains the Same - S5-E13
Factual error: When Anna travels back in time, she lands on the hood of a Pontiac trans am. Castiel later comments Anna is in the year 1978, but the the Trans Am Anna falls has the front end of a 1979-1981 model.

Hell House - S1-E17
Visible crew/equipment: When Dean, Sam, Ed and Harry have just shot Mordechai, the cameraman's arm is visible on the right-hand side of the screen. (00:33:30)
Dean Winchester: Driver picks the music. Shotgun shuts his cakehole.
Trivia: The inscription on John Winchester's gun is Latin, translating to "I will not fear evil."
Question: Why did Sam just stand there and watch Dean get turned into a vampire? And then smile about it?
Answer: Over the next few episodes, it is revealed that something is not quite right with Sam - that his soul is missing since he returned from Hell, and he does not feel any emotion or attachment to his brother.
