Wall Street is mostly a man’s world. Even as our economy has fallen apart, most of the people making headlines are male (and some go as far as to believe the collapse of the financial markets might not have happened if there had been more women involved). But Wall Street’s minority is being honored with an exhibit at the Museum of American Finance, an affiliate of the Smithsonian in New York City. “Women of Wall Street” runs through Jan. 16, 2010, and features five historical and five contemporary females who made a name for themselves in finance. After the jump, a quick intro to Wall Street women who led the way—and inspired us to contribute a little more regularly to our 401(k).

We’ve been so busy giving you gift ideas and sharing lessons our moms taught us, we’ve forgotten the meaning of Mother’s Day.

Mother’s Day became a U.S. holiday in 1914 after Anna Jarvis spent years sending letters to public officials urging them to set aside a day to honor mothers. Her own mother died in 1905. While Jarvis was happy when the day was recognized by President Woodrow Wilson, she became embittered by what it developed into over the years. “Mother’s Day has nothing to do with candy. Candy is junk. You give your mother a box of candy and then go home and eat most of it yourself, or else you give her hard candy that breaks her teeth or dentures. ... It’s really a shame to waste flowers for Mother’s Day. Florists have made millions of dollars out of my idea and they don’t deserve it.”

Instead of worrying about what to buy Mom during a last-minute shopping trip, why not spend the day with her or write a thoughtful note? But don’t use a printed greeting card. Jarvis disapproved of those, too. “A printed card means nothing except that you are too lazy to write to the woman who has done more for you than anyone in the world.” [Newswise]

The penis. So well-known, yet so enigmatic. For many women, the human penis remains one of life’s eternal mysteries. When we here at The Frisky Labs aren’t sitting around talking about our vaginas, we sit around talking about men’s penises. How do they work? Why do they look like that? What is the deal? We may not have answers, but we do have a lot of questions. In the spirit of better understanding this elusive member of the male anatomy, we bring you some of the most notorious phalluses in human history.

National Geographic takes us back through the history of bras. Did you know that by forgoing wearing corsets during World War I, women freed up enough steel to build two battleships?
