Gender: Male & Female

From the Washington Post Style Invitation, in which it was postulated that English should have male and
female nouns and readers were asked to assign a gender to a noun of their choice and explain their reason.

The best submissions:

ZIPLOC BAGS male, because they hold everything in, but you can always see right through them.
SWISS ARMY KNIFE male, because even though it appears useful for a wide variety of work, it spends most of its time just opening bottles.
KIDNEYS

female, because they always go to the bathroom in pairs.

SHOE

male, because it is usually unpolished, with its tongue hanging out.

COPIER female, because once turned off, it takes a while to warm up. Because it is an effective
reproductive device when the right buttons are pushed. Because it can wreak havoc when the wrong buttons are pushed.
TIRE male, because it goes bald and often is over inflated.
HOT AIR BALLOON male, because to get it to go anywhere you have to
light a fire under it... and, of course, there's the hot air part.
SPONGES female, because they are soft and squeezable and retain water.
WEB PAGE female, because it is always getting hit on.
SUBWAY male, because it uses the same old lines to pick people up.
HOURGLASS female, because over time the weight shifts to the bottom.
HAMMER male, because it hasn't evolved much over the last 5,000 years, but it's handy to have around.
REMOTE CONTROL female... Ha! You thought I'd say male. But consider, it gives man pleasure, he'd be lost without it, and while he doesn't always know the right buttons to push, he keeps trying.
