It's been a while since I've tackled an Editing Ninja post, but leave it to my students to provide inspiration.
Let's talk about personal pronouns, the first-person variety.
I is a subject. Use me when it's an object of a verb or preposition.
Incorrect: Vanessa and me like to watch old horror movies.
Correct: Vanessa and I love Vincent Price.
Incorrect: John invited Vanessa and I to his horror movie marathon.
Correct: John invited Vanessa and me to his horror movie marathon.
Simple, right? Eliminate the "___ and" and you can easily see which pronoun is correct. No one over the age of three would say "Me like to watch old horror movies."
Unless you are Cookie Monster.
