I think this sort of thing is the reason my cousin turned out to be a menace to society. When he was a toddler, he was a handful. "NO" had no effect on his behavior at all. But my aunt and uncle realized if they told him something was hot, he'd leave it alone. Leading to several years where everything was hot. Grandma's china cabinet? HOT. Bird house full of babies? HOT. Television remote? HOT HOT HOT HOT HOT.
I think it broke him because eventually he realized it was all lies and then he decided to live his life as the type of person who specifically touches stuff if you tell him its hot.
