Opening scene when the husband is choking up razor blades, he clearly spits up three razors. But in the next scene the wife states that the police found two razors on the ground, one in his throat, and one in his stomach.
At the very beginning when the wife comes into the kitchen with the candy, the baby is shown with stuff all over his face. When she picks him up to take him to his bath, his face is clean.
Samhain actually refers to a Celtic festival, and means 'Summer's end', not a mythological character called Samhain. There is a common misconception that Samhain referred to an ancient god of the dead. Also, "Samhain" is pronounced "SOW-in" (the first syllable rhyming with "cow") rather than "sam-hane," as it's pronounced in the episode.
While this may be true, the inspiration for the demon Samhain in this episode actually comes from "Sam Hain", the ghost of Halloween in The Real Ghostbusters who was, in turn, inspired by a fictional God of Halloween in Ray Bradbury's book, "The Halloween Tree". As these three are all fictional characters, the pronunciations of their names are, in fact, correct.
