Y'all need to be more careful about making stupid thread idea references in the FAC - some of us are completely unable to discern jokes from serious suggestions!
Just about any aroma in excess is going to become disgusting or even induce nausea at a certain point, but do you ever find that certain odors one might not normally think of as desirable are tolerable or even pleasant when exposure is brief/small. Unusual things like gasoline, musty material, tires, tar, sawdust, fresh paint, turpentine, or even skunk?
You know how like 2% of the population is not affected by poison ivy? I must be in that 2% where skunks are concerned, because unless I'm trapped in an enclosed area with the scent for a prolonged time, the smell really doesn't bother me. Gasoline is a scent that I actually find pleasant and will roll down the windows if driving past an oil refinery on a summer day. Newsprint is another smell that's not unpleasant in small doses. How about you - does anyone enjoy the scent of fresh paint?
Then there's the flip side of the coin too where you find pleasant, or unobjectionable smells becoming seriously UNpleasant after sufficient exposure. For instance I used to find the scent of frying food quite pleasant and was overjoyed the day I discovered that the scent of fried food seemed to be almost everywhere on the island of Okinawa. After a couple of months, though, I came realize there was no getting away from it and began to find it unbearable after a year! To this day the smell still causes a visceral reaction. Another example - I once dated a girl who wore a certain perfume all the time. I thought the smell was great when things were going well but oddly about the time the relationship began to go sour so did my liking for the scent. Maybe there's a stronger link to our olfactory senses and psychology than we realize.
