This reminds me of those horrible anti-drug classes they made us take when I was in school. We had to remember the slang terms for every drug and what each of them did.
So, apparently, if I smoked a joint, I’d immediately turn into some deadbeat and never have a life. And in reality, I knew people who smoked joints and were 4.0 students.
The obvious lying killed their credibility even when they were being truthful.
