What I have learned from American Gothic... SPOILERS!
In Boston, a police detective doesn't need a search warrant to get into someone's apartment. Just ask the assistant to the landlord. And when the cop leaves the apartment, he doesn't have to lock up so another person can easily come back in.
Doctors can leave private and exceedingly personal messages on a patient's voicemail (You're pregnant!).
The well-loved novel entitled Wuthering Heights is really pronounced WEATHERING Heights.
When holding someone at knife point and you ask them to throw their car keys on the ground in front of you, be sure to bend down and stare at the keys for 3-5 seconds giving the person a good chance to overpower you.
Policemen in Boston don't know their right from their left when describing dents on car panels.
You can kill a person by simply pinching their oxygen tube for a few seconds. (Definitely kill a cat that way since they don't know to breathe through their mouths!)

Female doctors don't use protection when they go overnight camping with men they hardly know.
Doors mysteriously close by themselves when you suffocate someone.
Artistic camera setups are a great way to make up for weak dialogue and/or plot development. The best way to film a close up of an actor or important action, is to have the principal waaaaaay over (annoyingly over!) to one side of the frame.
Virginia Madsen forgot how to act. (I've heard Botox has that effect).
A shaggy black wig can make any actor look 15 years younger, especially if the actor is really 65.
A police detective can break into a murder victim's apartment without permission accompanied by the main suspect in the victim's murder.
Digging up a body in an out-of-the-way locale after 15 years, which no one has reported as a missing person, is a good idea.
Drug-addicted, frantic parents can instantly recall their estranged spouse's Social Security number's last 4 digits.
After finding a missing child who has been abducted by a druggy parent, the only logical place to put him back to bed is in the druggy parent's apartment.
