Only half as powerful as a W-MD

I thought I’d excerpt a joke from an upcoming post — patience, flock — remembering a “Partnership for a Drug-Free America” TV agitprop spot from when I was in high school.  Over some hellish black-and-white scenes, the sad voice intones, “Nobody ever says, ‘I want to be a junkie when I grow up.’”

And my response was, “Well, I believe you just did.”

Please someone get the joke in the post title.  That’s even more important than telling me how many times you can say “agitprop spot” without getting tongue-tied (I’m at “one”.  At one with the that’s basically the joke in the title….)
