And finally, this was the week Len Goodman returned to the judges' panel, and he brought a whole lot of harsh criticism and technical know-how with him.
So let's take a look at some of the best, worst and weirdest moments of the evening.
Alfonso's Big Announcement
In the one of the sweetest moment from the season thus far, Fresh Prince of Bel-Air star Alfonso Ribeiro took time after his dance to wish his infant son a happy first birthday. Then he announced that he and his wife, Angel Unkrich, are expecting a brand new bundle of joy, much to the excitement of the cheering audience.
After weeks of our favorite English judge being M.I.A., Goodman made his return by stepping out of a jet black coffin and bellowing, "I'm baaack!" As it turns out, the stars should have taken this as a threat, because he cut deep all night. It was nice to have a judge that actually knows what good dancing is, unlike Jessie J and Pitbull.
Bethany and Derek's Devilish Dance
Set to the powerful and ominous "Run Boy Run" by Woodkid, and backed by demonic, hooded kettle drummers, Bethany Mota and Derek Hough brought a fiery passion to their Paso Doble. Also, Bethany's hair looked like a mix between Angelina Jolie's Maleficent and Gary Oldman's Dracula.
Janel's Pretty Little Liars Number
Janel Parrish and Val Chmerkovskiy's palpable chemistry was put to great use in a sexy, sharp, Pretty Little Liars-themed routine that ended with Janel and Val standing behind a white curtain, only visible as silhouettes. Then Janel clubs Val over the head, killing him. So romantic!
When Bruno Tried To Kill Julianne
Bruno Tonioli is a very physical person, and he often touches Julianne Hough in ways that really just make everyone uncomfortable. So things got really weird when Bruno accidentally grabbed Julianne and then fell out of his chair, pulling her down on top of him. Julianne might need to invest in some mace.
Who knew it was possible to make The Charlie Daniels Band's "The Devil Went Down To Georgia" boring? The race car driver and his pro partner Emma Slater were supposed to be doing a jive and that jive was set to one of the fastest country songs there is -- but Michael's slow, lumbering stumble just wasn't up to snuff.
Tommy Chong' Uncanny Ghost Resemblance
Tommy Chong and Peta Murgatroyd dressed like '20s-era socialites and danced to Frank Sinatra's "Old Black Magic." While Tommy impressed the judges with his quick step, the most amazing part of the whole performance was how much Tommy Chong wearing a top hat looked exactly like a ghost from Disneyland's Haunted Mansion. On a side note, it was revealed that Tommy was the oldest celeb to have ever made it this far on DWTS, which brought a proud tear to Peta's eye.
Janel Parrish Could Be A Scream Queen
Because it's a Halloween episode, the producers thought it would be hilarious to scare the stars and pros by having people in creepy clown masks startle them. Well, it wasn't exactly hilarious, but it did prove that Janel had what it took to be one of cinema's classic scream queens. When a masked monster startled her during a pre-recorded interview she screamed her lungs out and, like anyone in a horror movie, simply froze up in fear.
While this was actually one of the more entertaining performances of the whole night, the routine was just too weird to ignore. Mark Ballas was the dead-eyed zombie leader of a group of flesh eaters, and they chased Sadie -- who was dressed like an 11-year-old girl with a teddy bear -- around a graveyard. Despite the dancers' best efforts, most of the judges felt like the props, costumes and story over-shadowed the routine.
Bethany Mota and Derek Hough - 39
Alfonso Ribeiro and Witney Carson - 36
Lea Thompson and Artem Chigvintsev - 34

ELIMINATION (WARNING: SPOILERS)
Alfonso, Sadie, Antonio and Tommy ended up on the chopping block at the end of the night. As expected, Alfonso and Sadie were immediately safe, meaning it really came down to Tommy and Antonio.
Unfortunately, Antonio just couldn't keep up with the pace of the show and ended up getting the axe. Meaning Tommy Chong extends his record of "oldest contestant to get this far" even further.
Next week, DWTS pays tribute to the great dynamic duos in history and pulp culture including, as host Tom Bergeron informs us, "Romeo and Juliet, Bonnie and Clyde, Batman and Robin [and] Adam and Eve."
