The catalog says that they do not encourage smoking, and that the donkey is intended to be a collectible reminder of a bygone era, so it comes with a display case. And, of course, it wouldn't be in the catalog if it didn't sell. In other words, there are people in this country who can look at a plastic mule with a cigarette coming out of its ass, and think, "Boy, wouldn't that look great displayed on the mantelpiece?"
