Got my first Perfume movie, smart-ass remark from someone when I told them that I make natural perfume.
"So, how many girls do you juice in a typical week? Har har har har!"
I got the same thing when I had the soap store ~ in reference to 'Fight Club'.
Oh, and this one isn't related to perfumery or soapmaking, but thought it merited the 'could you say anything more stupid' medal of honor: Ask the cheese person at Wholefoods to cut a chunk of cheese for you, and every grown adult male within ten feet will grin and say, "Look, she's cutting the cheese." If they don't say it, they're at least grinning and thinking it. These are rolling pin and skillet moments.
