My mom is seven years older than John Mulaney. She grew up in Chicago just like he did.
I called her tonight on a hunch, and asked if she knew the name JJ Bittenbinder. And she does. She remembers seeing him at least twice, in fourth and fifth grade. He discussed household poisons, self-defense for young girls, and word-for-word told them that if they went to a secondary location, their chances of coming back were SLIM TO NONE.
Considering what my mom taught me as a little kid, this is how I realized that I indirectly learned a lot from Mr. Bittenbinder, via my mother, without ever realizing it.
