Was your dad active on 4chan in 2012?And thus a new scientific mind is nurtured.
According to legend (read, my grandma), my father had a similar story.
Grandma continuously told him "don't touch the stove, it's hot!", but he kept trying to touch it. Didn't believe her, I guess. One day, grandma had enough. My dad climbed up to the stove again, and grandma didn't intervene. Dad touched the stove, and surprise, surprise, burnt his hand.
He never tried to touch the stove again.
