Handwriting:
Men: To their credit, men do not decorate their penmanship. They just chicken-scratch.
Women: Women use scented, colored stationery and they dot the "i" with circles or hearts. Women use ridiculously large loops in the "p" and "g". It is a pain to read a note from a woman. Even when she's dumping you, she will put a smiley face at the end of the note.

Sex:
Women: They prefer 30-40 minutes of foreplay.
Men: They prefer 30-40 seconds of foreplay. Men consider driving back to her place part of the foreplay.

Maturity:
Women: They mature much faster than men. Most 17-year old females can function as adults.
Men: Most 17-year old males are still trading baseball cards and giving each other wedgies after gym class. This is why high school romances rarely work out.

Shoes:
Women: When preparing for work, a woman will put on a wool suit, then slip on Reebok sneakers. She will carry her dress shoes in a plastic bag from Saks. When a woman gets to work, she will put on her dress shoes. Five minutes later, she will kick them off because her feet are under the desk.
Men: A man will wear the same pair of shoes all day. Let's not talk about how many days he'll wear the same socks.

Cats:
Women: Women love cats.
Men: Men say they love cats, but when women aren't looking, men kick cats.

Eating Out:
Men: When the check comes, each man will each throw in $20 bills, even though it's only for $22.50. None of them will have anything smaller, and none will actually admit they want change back.
Women: When the girls get their check, out come the pocket calculators.

Friends:
Women: Women on a girls' night out talk the whole time.
Men: Men on a boy's night out say about twenty words all night, most of which are "Pass the Doritos" or "got any more beer?" or "WOW...look at the hooters on that!"

Restrooms:
Women: Women use restrooms as social lounges. Women who've never met will leave a restroom giggling together like old friends. Women also go to the restroom in packs, at least two women at a time excuse themselves to use the restroom.
Men: Men use restrooms for purely biological reasons. Men in a restrooms will never speak a word to each other. And never in the history of the world has a man excused himself from a restaurant table by saying, "Hey, Tom, I was just about to take a leak. Do you want to join me?"

Mirrors:
Men: Men are vain and will check themselves out in a mirror.
Women: They are ridiculous; they will check out their reflections in any shiny surface: mirrors, spoons, store windows, bald guys' heads.

The Phone:
Men: Men see the telephone as a communication tool. They use the telephone to send short messages to other people.
Women: A woman can visit her girlfriend for two weeks, and upon returning home, she will call the same friend and they will talk for three hours.
