Men, have you ever experienced sexism personally?

Some subtle and some not so subtle. Obviously I do more "manly" chores around the house while my wife does things a woman stereotypically does, but this is not sexism. I was once passed up for a promotion by a younger, less experienced female colleague. I raised hell about it to my boss and human resources department and the issue was eventually solved. I see prejudice against men in the media all the time. They are often portrayed as stupid or clueless in commercials.
