Thank you for supplying the joke-—I didn’t have time, but it did strike me as a possible example of a mortal sin involving the environment. I heard it in a homily a few weeks ago (in rural Ontario), and recalled the first time I heard it, two or three decades ago, also in a homily, in rural Oregon.
I’d never heard it; so I had to check it out.
