Continuity mistake: At the beginning of the movie when the main character and his friend are sitting in the break room having a conversation about getting old and their friends dying, the straws in the drink cups on the table and the paper sleeves on the straws appear halfway through the conversation.
Continuity mistake: When the three girls decide it's high time to make their own sorority, they begin to jump all over the place excitedly. Nora for the greater part of the scene has worn big pink glasses on top of her head, but they are in her hand as the jumping ensues. However, cut to Dustin shouting at them from the door, and Nora's glasses are back on her head. (00:12:25)
Factual error: In the scene when they are locked in the garage, they attempt to use vehicle air bags to propel themselves through a garage vent in the roof. It is absolutely impossible for a air bag to deploy by jumping on it. A air bag requires specific battery voltage and resistance supplied by a air bag control module to deploy a air bag. The physical act of jumping on it will not deploy it.
