My Three Sons - Season 12 Episode 24 Whatever Happened to Ernie?
6.50 30 minutes Steve's boss Bob Anderson and his wife share 'Where-did-we-go-wrong?' panic as they struggle to communicate with their son; Steve and Barbara are the counselors. The teenager is rude and disrespectful to his parents but his insolence doesn't bother them nearly as much as not knowing if he is taking drugs.
