It is fun, having intelligent children. Was trying to remember a phrase. I have an odd memory. I cannot remember a person's name, told to me moments ago, but came recall an interesting notion from decades back.
There was a quote. Something like "Confuse the idiots", but deliciously subtle. I could not recall the exact phrase, so my daughter started hammering at Google, trying to find variants. Not sure that we found (eventually) the exact phrase, but this comes at least close in subtlety:
When in doubt, confuse the innocent.
Sometimes I think, as a Father, I did not completely screw up. :)
