If you wash an assortment of water bottles, take a photograph of them
first, or take some other stern measure to make sure you get each
bottle back together with its own lid. If two bottles of different
brands -- or the same brand from different production runs -- appear
to have interchangeable lids, the lids will differ exactly enough to
make the bottle leak, but not quite enough that you will notice when
you screw the lid on.

Or mark the bottle and its lid with a waterproof indelible pen :-)
