ZIPLOC BAGS: Male - because they hold everything in, but you can
always see right through them.
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; and because it can wreak havoc when
the wrong buttons are pushed.
TIRE: Male - 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 it would be 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.
