So, yeah, its a good time.

Lets run through the dances, which arenotin chronological order of assigned decade, becauseDWTSlikes to keep you guessing.

Instead, theyre off to Lauries first prom.

She even gets a corsage.

If only all proms looked like this one.

And if only all prom dates did splits like Val.

The duo dances a fun, bubbly quickstep.

Most of the judges love the blend of lightness with Lauries inherent strength of movement.

Its Len, of course, who finds fault with a lot of Lauries technique.

Val brushes it off, though, citing Lens obvious jet lag.

Vals so cheeky tonight.

Just get Laurie home before curfew, okay?

Animal crackers make me feel things now.

So, yes, Aerosmiths weepy anthem screams the 1990s to me.

Its the most tragic love story of our time!

Theyve basically given up on Ryan improving technique-wise, so its all about getting into character.

InArmageddonterms: He needs to be less of a Colonel Sharp, and more of a Harry Stamper.

Marilu Henner and Derek Hough, 1920s

Charleston, Never Forget You by Scott Bradlees Postmodern Jukebox feat.

Addie Hamilton

Marilu once played Roxie Hart in a production ofChicago, so shes feeling the Charleston.

Derek, on the other hand, is having trouble with the two-dance week.

We dont feel bad for you, you glorious starfish.

Unfortunately, Marilu may have overcompensated for feeling comfortable in her dance style.

Bruno points out the end was a big ol mess.

They did capture the essence of the decade, though, plus Derek did some tap dancing.

There are also points to be had for tap dancing.

Judges Score: 29/40

NEXT: Lift free since 53!

They arent allowed lifts in the jive, though, so its all about crisp, clean footwork.

Lindsay instructs him to focus all his energy on his feet and the judges will take notice.

The judges commend him not only on his high energy, but also his excellent technique.

Len, especially, is proud to see his improvement over the past few weeks.

They dont need no stinkin lifts!

Artem tells us its his first time ever wearing one, but he promises it wont be the last.

How lucky we are to be alive right now.

She loses steam and there are several stumbles.

But Carrie Ann loves that even though she went wrong, she kept going.

She also suggests some more body contact while in hold.

Team 80s needs to pull it together before the team dance.

Sasha wants his girl to shake it off.

To help remind Terra what shes doing this for, her husband and two kids show up to rehearsals.

Terra wants to show them how to push through obstacles and accomplish goals.

So, out on the dance floor she goes!

She and Sasha dance a lovely, elegant foxtrot.

They look so in sync and connected, and Terra is back in her comfort zone.

That wonky paso is completely forgotten.

What a perfect pairing.

No shower is safe anymore.

The samba is fast and its not coming as easily to her as she and Gleb would like.

Things get tense, there are tears, but Team Hotties settles into it.

They put forth a disco-era samba set in a laundromat.

According to Americas Dad Tom Bergeron, this is historically accurate.

Unfortunately, according to Len, the routine isnt accurate to the dance style.

Our Head Judge and Gleb get into it and everyone is very uncomfortable.

Cant it be both?

Sure, Laurie and Val were favored from the start, but James is a real contender.

Also, he takes care of our girl Sharna when she needs it.

Sharna injured her knee during dress rehearsal, but still dances their 1940s jitterbug because shes a champion.

The judges love the theme and choreography and Julianne is left wanting more, but in a good way.

She also says they always dance as if its their last.

This better not be some ominous sign!

Heads will roll, butnotin the good way.

Laurie goes for girl power and James gets the athletes (plus Maureen).

But when they get on the dance floor, that theory goes out the window.

They dance a gorgeous Viennese waltz to a Scottish folk song, also known as the theme fromOutlander.

Team Past was completely in sync with one another and it was a true team dance.

Carrie Ann calls it her favorite of the night.

Terra is having the toughest time.

Terras embarrassed and doesnt want to hold her team back, but they eventually work it out.

The concept is cool, but maybe not as effective from my seat.

Its not as clean as Team Past.

Its starting to look like Laurie doesnt have the trophy in the bag just yet.

But before we can begin speculating on who well see in the finals, theres an elimination to announce.

), but the journey is over forMaureen and Artem.

This better not sour Artems new affinity for wigs.
