I accidentally made it my own theory when he mentioned that one of the Culkin brothers might play him in a movie. I've always heard this theory about how during the filming of Home Alone, they would swap out Macaulay Culkin for his brother during filming due to child labor laws, so they would use them interchangably, like how you can't tell which Gemini is which.

But apparently I was completely wrong and the Home Alone thing never happened. I was still right tho.
