For me I love the smell of puppy breath and my dogs paw fur. I like Hopps gun oil to use when I clean my gun as it has a very unique aroma. As a child I loved the smell of my grandpa's medicine called Paregoric(smells like anise). I just found a bottle on ebay and it brings me back to my childhood when I smell it. Cant believe I bought old meds laced with opium on ebay,lol.
