During discussions on the internet about intent, I have thought of ways that would be foolproof. Not my kids, it never occurred to me to do it. My imagination doesn't involve my children or anyone I know, nor would I ever do it.
But when I'm in a discussion about something that was either planned or accidental my mind has wandered. At the time I mentioned it, a lot of people piped up and said "I KNOW!! HAHA that's what you get from being on Websleuths! An active imagination and a knowledge of an investigation."
As plans go, this one here isn't a very good one. Especially since he's being accused of planning it down to the most incredibly minute detail.
