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 nouns of their choice and explain their reason.

The best submissions:

 

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.

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.

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.

ZIPLOC BAGS -- male, because they hold everything in, but you can always see right through them.

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; it hasn't evolved much over the last 5,000 years, yet it's still handy to have around.

REMOTE CONTROL -- female...Ha!...you thought male. But consider, it gives a man pleasure, he'd be lost without it, and while he doesn't always know the right buttons to push, he keeps trying.
