I love the smell of diluted skunk. I inhale deeply as I drive through a sprayed area and I'm sad when the odor is gone. And gas - I love the smell of gas. I know inhaling a bunch of hydrocarbons are not good for the lungs; it says right there on the gas pump. I don't go out of my way to do so, but I do have fill the tank up every so often. Just like with the skunk, I don't want the full blast, but a fine mix of air and stink.
