My brother and I were always pretty good at both self-deprecating and brother-deprecating jokes with one another. It’s a habit we can fall into pretty smoothly when we see one another, much like our discussions of comics, movies, and various and sundry geekery.

What a charming and handsome fellow you have introduced to your cast!
What? Ronnie has been in it from the start!
Welcome to the cast of “Lifeofronnie” David!
I am a little confused about the “brother-deprecating jokes”, though. I always thought you were just a jerk!
Dave? Dave Routly? All grown up and living in the desert? C’mere, ya big lug!
