Soup - I haven't purchased Campbell's soup since, well not sure I ever have, so hard to measure my observations on that.
Matches - Same thing.
Drain - As pointed out, a myth.
VHF - Already discussed.
Fans - Same problem as merry-go-round, which direction depends on from behind or in front, and there may be a standard for it but there's no compelling reason they go one way or another. I was thinking of my CPU fan for this one so got it wrong.
Lug Nuts - All cars are the same I guess.
Blinds - You can specify which side you want the cords or rods on when you order them.
(Yes, I'm just bitter because I got the no smoking one wrong)
