Factual error: (Season 4) During the episode where Ms. Grubman and Christian are talking in his office and he turns around a few seconds later to see she had died while in her wheelchair, her head and posture is still straight up and forward - near impossible. Common physics tells us that upon death, her head would have either drooped backward, downward, or to one of her sides.
Factual error: At the onset of the episode, Christian and his blind girlfriend decide to go to a movie rental place. While Christian goes inside, he leaves his gf in the car and the song "Love Will Keep Us Together" by Captain and Tenille is playing. During this time, two young guys pull up in a van and find out the girl is blind and then decide to strip Christian's car of all 4 wheels and the front end. Christian comes out about three minutes later (the end of the same song is nearing) to see his car sitting on 4 jacks and void of any wheels or front end. Given the time that Christian is gone which is just a few minutes, it is nearly impossible for even a team of multiple seasoned pro thieves with the most sophisticated auto equipment to disassemble part of a car (and those specific parts) in that small amount of time, let alone two kids just passing by deciding to do so on the spur of the moment.
