In Army Basic Training, one afternoon, I had a 2nd Lt threaten to punish me for not shaving. I explained that I did shave that morning, but it the stubble he saw was from growth that day. I considered telling him that he would learn that fact personally after he hit puberty, but I held back that thought.
With the robocalls, I hang up. But if I get a live person I start with “long time no hear” then segue into asking about how their sister is handling her drug rehab, or their brother is managing his prison time for being a child molester.
That is the joke.
