Not to hijack, but.... here's another one.
I have a sailboat that we race pretty much every week and as such the winches (8) have to be serviced a minimum of 2 times a year. To service them you have to take them off the boat, tear them down to gears, springs, and tiny pieces of metal. then clean each part with engine cleaner to remove the old grease and oil. Then you inspect, reassemble, and re-oil and grease the parts. it's stinky, sticky, gross work and takes about 2 hours to do each winch. The grease is lithium grease and has a distinctive scent, as does the engine cleaner, which reminds me of the smell of an auto rebuild shop.
After a full day of cleaning and rebuilding winches I took a hot shower to scrub all the grease that managed to get everywhere not covered by clothes. I crawl into bed pink from hot water and a loofah and pick up my book to read for a bit. After a few minutes my husband leans over and sniffs. Then he leans further and sniffs again and says. "You smell like petroleum distallates...." and then in Paris Hilton style "that's hot." Of which I couldn't stop laughing. Which of course spurs him further, "I bet Martha Stewart can't tear down and rebuild a 3 speed winch on her kitchen counter in less than 2 hours, she's not hot."
I swear I have no idea where he comes up with this stuff. But it's sweet, sort of like telling a shy girl in our dive class that there is nothing more alluring than a woman with salt spiked hair and snot running down her nose after a dive.
