Continuity mistake: The grilled cheese sandwich was charred while it was still cooking, but not when Jason's dad served it to him. (00:02:00)
Deliberate mistake: Noel's mother was removing a tray of cookies from the oven as Noel was walking into the kitchen. Noel was able to pick up a hot cookie from the also hot tray without burning his fingers, but he did burn his tongue after taking a bite. Even IF Noel could touch a cookie without burning his fingers, a hot cookie is not easily removed from the tray and it would collapse - not hold its shape (unless overcooked to a crisp). (00:16:43)
