I think they do? but I might be playing too much monster hunter. Unless you were talking about dragons, liches, or durgons. In which case I'd say "I think it's part of the original myth?", "Only for attention whore-liches who like special effects.", and "A fire breathing fish, that would be really good. If you know how to make that happen, I'll put you on my payroll to get them created and distributed across the worlds oceans."
Also, when "breathing clean air" involves shoving your face into an old dog blanket, you know there is a serious funk in the air.
