15 differences between guys and girls

Found this on boundless.org and they're pretty funny and true. The last one has got to be my favorite.
1. Even though a guy has 50% more brute strength than a girl, she is able to withstand higher temperatures than he can.
2. A girl has a larger stomach, kidneys, liver, and appendix than a guy, but she has smaller lungs, thus giving her less breathing capacity than a guy.
3. The right hemisphere of guys’ brains are better developed, therefore they are more visual, mathematic, exploring, more sex oriented, and commit most violent crime. Girls, though, have the left hemisphere more developed and are therefore more verbal, communicative, sensitive, and more prone to phobias and depression.
4. Guys use restrooms solely for biological reasons — to drain their bladder. Girls, on the other hand, use restrooms as social lounges. Guys will never speak a word or make eye contact with others they don’t know there. But girls who’ve never even met will, by the time they’re finished, leave laughing out loud together like old friends.
5. When the restaurant check comes, each of the guys will throw big bills out on the table to supposedly pay for the tab. When the check comes for the girls, each will get out her calculator to verify the total and figure her down-to-the-penny part.
6. All week, a girl will thoughtfully make an extensive list of things to purchase at the store and when she arrives, she walks directly from item to item, comparing prices and coupons. When the frig is empty and starting to grow things, a guy will just show up at the closest store and start cruising up and down every aisle, throwing in his basket anything that looks appealing. Even though his cart is jam-packed, he will try to butt in the 10 items-or-less checkout line.
7. A guy has five items in his bathroom — a razor, shaving cream, a bar of soap, a toothbrush, and towel from Holiday Inn. The average number of items in a typical girl’s bathroom is reported to be as high as 437, the majority of which a guy couldn’t even tell what they are or used for.
8. When a girl says she will be ready in five minutes, she’s using the same meaning of time as when a guy says the football game has just five minutes left to play. Neither the guy nor the girl is counting time-outs, commercials, or replays!
9. A girl believes that visitors will be impressed by a clean house. A guy believes the visitors will be impressed by his large stereo.
10. Guys don’t decorate their handwriting, they just chicken-scratch. Girls will pull out their scented, color coordinated stationary and use ridiculously large circles, hearts, and loops to finish off their “i’s”, “p’s”, and “g’s.” It is a real hassle to read a letter from a girl. Even when she is dumping a guy, she’ll finish it off with a smiley face at the end!
11. If a girl is out driving and she finds herself in unfamiliar surroundings, she will stop at a gas station and ask for directions. Guys, of course, consider this to be a sign of weakness. A guy will never stop and ask for directions. They will drive in a circle for hours, all the while saying things like, "Looks like I've found a new way to get there," and, "I know I'm in the neighborhood. I recognize that Ace hardware store."
12. With the exception of female bodybuilders who call each other names like "Ultimate Pecs" and "Big Turk," women disdain the use of nicknames. If Amber, Suzanne, Katherine, and Natalie get together for lunch, they will call each other Amber, Suzanne, Katherine, and Natalie. But if Mike, Dave, Rob, and Aron go out on the town, they will affectionately refer to each other as Bullet-Head, Godzilla, Peanut-Brain, and Yard-Dart.
13. A girl worries about the future until she gets a husband, while a guy never worries about the future until he gets a wife.
14. A girl marries a guy expecting him to change, but he usually doesn’t. A guy marries a girl thinking she will always be the same — and, of course, she isn’t.
15. Girls love cats. Guys say they love cats, but when girls aren’t looking, they kick cats.
