FREEZER BAGS
They are male, because they hold everything in, but you can see right through them.

PHOTOCOPIERS
These are female, because once turned off; it takes a while to warm them up again. They are an effective reproductive device if the right buttons are pushed, but can also wreak havoc if you push the wrong buttons.

TIRES
Tires are male, because they go bald easily and are often over inflated.

HOT AIR BALLOONS
Also a male object, because to get them to go anywhere, you have to light a fire under their butt.

SPONGES
These are female, because they are soft, squeezable and retain water.

WEB PAGES
Female, because they're constantly being looked at and frequently getting hit on.

TRAINS
Definitely male, because they always use the same old lines for picking up people.

EGG TIMERS
Egg timers are female because, over time, all the weight shifts to the bottom.

HAMMERS
Male, because in the last 5000 years, they've hardly changed at all, and are occasionally handy to have around.

THE REMOTE CONTROL
Female. Ha! You probably thought it would be male, but consider this: It easily gives a man pleasure, he'd be lost without it, and while he doesn't always know which buttons to push, he just keeps trying.
