I'm trying to end all my sentences with the phrase "in these dark times" and it's working to great effect.
Such as, "We'd better go to the store today. We don't want to run out of milk in these dark times." And, "Z, paint while you can. This may be the end of expensive crayola paints in these dark times." "Extra butter on my English Muffin. You can't fatten up too much in these dark times." This sentence changes it up a bit: "The house can stay messy. In these dark times, the dirt and dust may be the only thing we actually own." "Dear Students, You've asked and I've finally agreed. In these dark times, you don't need to be on time, turn in your papers on time, or participate in workshop. The University may not even be here by the end of the semester."
You get the drift. See how much more fun this is than talk like a pirate day? Talking like a doomsayer comes more naturally to me. And has I hope a cathartic more than a prophetic effect.
