31 Things Mary-Kate & Ashley Taught Us

When Mary-Kate and Ashley Olsen appeared on Ellen on Friday, it was a big deal. The world's most famous twins hadn't been on TV together since 2010, leaving a generation of fans to rely on tabloids and fashion show photos to keep track of them. But as great as it was to see Mary-Kate and Ashley on TV again, it only reminded us that they're all grown up, just like the rest of us. So when you're missing the good old days of the 90s, when the color-coordinated twins would travel the world, solve mysteries, and throw great parties, you're better off revisiting their old classics. It turns out, you might actually learn something.

Those old Mary-Kate and Ashley movies are filled with important life lessons. You might've picked some up without even realizing it, after watching Passport to Paris or The Case of the Logical I Ranch for the hundredth time. But if you need a refresher course, you're in luck. Many of the movies are available in full online, thanks to YouTube user MaryKateAshleyFans. If you don't have time for an Olsen marathon, however, don't worry.
