You may not know this, but many nonliving things have a gender. 

1. Ziploc Bags are Male because they hold everything in, but you can see right through them. 

2. Copiers are Female because once turned off it takes a while to warm them up again. It's an effective reproductive device if the right buttons are pushed, but can wreak havoc if the wrong buttons are pushed. 

3. A Tire is Male because it goes bald and is often over-inflated. 

4. A Hot Air Balloon is 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. 

5. Sponges are Female because they're soft, squeezeable and retain water. 

6. A Web Page is Female because it's always getting hit on. 

7. A Subway is Male because it uses the same old lines to pick people up. 

8. An Hourglass is Female because over time the weight shifts to the bottom. 

9. A Hammer is Male because it hasn't changed much over the last 5,000 years, but it's handy to have around. 

10. A Remote Control is Female. Ha! You thought it would be male, didn't you? But consider this - 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.
