That would be interview suicide wouldn't it???
Only i have been invited for an interview, its an admin position in an engineering company. When i spoke to the guy he was one of the types that you could tell was totally out of his comfort zone with interviewing. I suspect he was the manager and not the personell manager if you see what i mean. This surprised me as its a big company.
Anyway, when I asked if i should bring anything (im used to being asked for qualifications, id etc - it always causes me a problem as i have no valid passport and i dont have a driving license), he just flapped a bit and said, "ah no, just bring some ice creams for the girls!" My initial thoughts spun between, hmmm, he sounds like he might be ok, or he could be a sexist twunt. So i blustered too and said, don't be mad its winter, i'll bring doughnuts instead. It was ended tht i should just bring a smile!!! 
So what if i did actually take the doughnuts? would he think i was
a) barking mad
b) a sychophant
c) quirky with a sense of humour
A friend of mine who is a manager in an engineering company said to me "i hope you ARE going to take the doughnuts" and my DP said "don't be ridiculous"
