At the end of "I'm with Stupid" Marty states "Oh that's right, honey. We don't have a son!" It is unclear of how Marty and Janet knew Patrick's name.
SpongeBob clearly says "What Not to do at a Stoplight, by SpongeBob SquarePants", as he writes it on his paper. A later shot of SpongeBob's paper clearly says, "What not to do at a Spotlight, By: SpongeBob Sqaurepants". It says "Spotlight" instead of "Stoplight".
After Spongebob writes the title to his paper, it should read, "What Not To Do At A Stoplight". However, when they show it, it says, "What Not To Do At A SPOTlight".
