A Perfectly Deer Shaped Steam Puff

Last night I was driving around a ritzy neighborhood part of town looking at Christmas lights with my wife. I saw a small white tangle of wire shaped into the form of a reindeer. This got me to thinking. I bet a couple times a year, somewhere around the world there are dryer vents or chimneys or HVAC exhaust ducts that billow out a small puff of steam in the perfect shape of a deer--horns and all. I bet if you're one of those lucky people who gets to see it happen, you'll smile and think to yourself, "Damn! Was that puff of steam looked just like a deer."
