Mary-Kate and Ashley Olsen may have officially traded in their on screen careers for behind the scenes fashion fame when they turned down the opportunity to appear in the Netflix series Fuller House. Although their primary focus is now on their label The Row and Elizabeth and James, their luxury wear, for millennials the twins’ legacy will always lie in their total domination of ’90s entertainment. As they celebrate their 30th birthday today, let’s take a look back at the best of the best.

5. Mary-Kate and Ashley Olsen: Greatest Hits

Although, shamefully, they were never recognized by the likes of the Grammys, the Olsen twins ruled the ’90s with their absurdly catchy, often politically incorrect tunes. Before the era of Craigslist and eBay, the best way to advertise merchandise was through song, which Mary-Kate and Ashley perfected through “Brother for Sale,” an attempt to get rid of their least favorite sibling. They also taught me everything I need to know about politics with “No One Tells the President What to Do,” which I’m hoping Hillz uses as her anthem during her next speech on the campaign trail.

4. You’re Invited to Mary-Kate and Ashley’s

This direct to video series ran from 1995-2000, and each episode gave viewers VIP passes to the legendary parties the twins threw. The Olsens knew how to throw it down on the party scene, whether it was sleepovers, camp outs, or *gasp* their very own birthday celebration. You weren’t cool if you didn’t watch Mary-Kate and Ashley’s sleepover episode at every sleepover you attended in the early tween years. Plus, these girls are the sole reason I started wearing overalls and neon, backwards baseball caps.

3. It Takes Two

Two unrelated yet identical children switch places and decide to play matchmaker with their parents. Ah yes, the ultimate The Parent Trap wannabe film. Viewers will never stop wondering how it’s possible for a child’s family not to realize their daughter is, well, not actually their daughter. But that’s neither here nor there. Mary-Kate and Ashley loved to emphasize the idea of differences in their films, so of course It Takes Two revolves around two families that drastically differ in income and way of life, only to brought together by love, and two adorable blondes of course. And of course, the highlight of the film is the inclusion of the family of the “Butkises”.

2. Full House

The television show that spawned years of stardom, Full House revealed baby Michelle, a shared role that would continue to define (haunt?) the twins for years to come. Full House is the quintessential ’90s sitcom, whose popularity has never died, as is evident in the revival of the series by Netflix, released earlier this year. Michelle was the heart and soul of the show, quipping the one liners we millennials continue to use on a regular basis. Want to escape for thirty minutes into the home of the most joyfully dysfunctional family to ever fit in one home? You got it, dude.

1.The Adventures of Mary-Kate and Ashley

Whether the preferred method of devouring the mayhem and mystery was watching an episode on TV or reading about their escapades in the companion books, the twins never failed the promise they made to their fans to “solve any crime by dinner time” along with their basset hound Clue. Move aside Nancy Drew, because this is really where my love for whodunnits began. The sassy sleuths sure did get around, helping everyone from Santa to the United States Navy. The majority of my preteen years were spent splitting my time between The Adventures of Mary-Kate and Ashley and the PBS show Wishbone. Damn I miss the ’90s.
