When Johnny Sack forgets the sweater and goes back to his home, he finds Ginny in the basement, covering a box of hidden candies and snacks with some laundry. When Johnny removes the laundry to reveal the box, a Milky Way Midnight Dark is resting slightly on top of a package of Skittles and a bag of Combos is visible, but when they show the box again, the Skittles are now covering the unseen Milky Way and the Combos are gone.
When Johnny is talking to Carmine, Carmine's hands are seen folded at the end of the scene, but when the camera angle changes, they aren't.
In John's office on the the side table is an upside-down orange pizza box from Pizza Pizza. Pizza Pizza, with that particular logo, is a Canadian pizza franchise and has never expanded outside of Canada. It is odd to see that in this New Jersey setting.
While Ralph is supposedly in Miami, he rides in an elevator where an inspection certificate that says "City of New York Department of Buildings" is clearly visible.
