Reread the beginning of this essay about a specific form of humor. “Did you see that crane?” As we walked through downtown Victoria, British Columbia, admiring the new scenery, my brother pointed off in the distance. “The actual crane, not the construction crane.”

I craned my neck, peering into the distance to look for the thin white bird. “Technically they’re both actual cranes. It’s not like construction cranes are fake.”

Finally, I spotted it, pecking at the sandy beach to find its dinner, the tall buildings of the city silhouetted behind it. Far in the distance, there were construction cranes as well.
