One cold night my furnace died, so I went to my parents’ house. In the morning, a neighbor called to tell me that my water pipes had burst and flooded my town house and hers. I raced home—and on the way got a speeding ticket.

Then the furnace repairman arrived and told me he didn’t think he had the proper fuse but would check in his truck. Meanwhile, the plumber cut holes in my bathroom wall to locate the leak.

When the furnace repairman returned, he held aloft a fuse. "I had the right one," he said triumphantly. "This must be your lucky day."
