It’s a truth universally accepted that the bond between fathers and daughters belongs to one of life’s most irreplaceable treasures. New dads of little girls often sense, almost instinctively, that they must tread with a gentler touch—protecting, nurturing, and trying their hardest to understand emotions they’ve never experienced themselves. Many fathers will gladly bend over backward to keep their daughters happy, but very few are prepared to memorize Beyoncé’s “Single Ladies” choreography, wriggle into a skintight leotard, and then perform the whole thing in front of an actual audience and allow the evidence to live online forever.

Yet somehow, exactly one man stepped up to the challenge—Steve Haddad of Monroe, Michigan. In December 2017, Steve decided dignity was negotiable, but making his daughters laugh was not. So he pushed every doubt aside, teamed up with his two eager girls, and agreed to deliver a holiday performance that would go down in family history. The result? A living-room dance sequence no one present would ever, ever forget.

With their game faces on, the trio—and especially Steve—held absolutely nothing back. From the moment the music started, he committed to every hip swivel and hand flick like he’d been preparing for a world tour. Their living room transformed into a makeshift stage, their guests into a stunned audience, and their family’s Christmas tradition into an unexpected viral sensation waiting to happen.

Steve and his wife, Tina, have always gone the extra mile for their kids, so it didn’t surprise anyone that he’d eventually say yes. He’s the kind of dad who would do just about anything if it meant his daughters would break into smiles. According to Tina, the family hosts an annual Christmas Lip Sync battle—and the girls had their hearts set on performing “Single Ladies.” They weren’t joking about it either. They wanted the routine right, and Steve knew he had to give their idea genuine effort if he was going to take their request seriously.

Tina told Scary Mommy that the girls practically begged their dad once she floated the Beyoncé idea. “The girls were trying to come up with a brilliant idea to beat the competition, which in this family is tough,” she said. “I threw out the Beyoncé ‘Single Ladies’ video. The girls BEGGED him and because he loves to make us laugh, through much nagging on our part he agreed.”

The three of them practiced the choreography for weeks. But what Tina didn’t expect was what happened on the actual day of the performance. Steve had never rehearsed in a leotard—so when he strutted into the living room in full costume, Tina nearly fell over. She had no idea he was going to commit at that level.

And then the performance began. The results were everything a family could hope for: hilarious, joyful, slightly ridiculous, and absolutely unforgettable. The entire routine was filmed and uploaded to Tina’s Facebook page, where Steve—pouring himself into that leotard—hit almost every move with impressive dedication. Even with laughter erupting behind the camera, he stayed focused, determined not to fall behind his daughters. He missed a beat or two, sure, but he never stopped trying. By the end, it was obvious how far he was willing to go to make his girls’ night magical.

“You asked you received… Haddad Lip Sync contest. Stay back girls he’s all mine!!! #BESTDAD #Beyonce #allthesingleladies #christmaslipsync,” Tina captioned the now-famous video.

“Awesome!!! I have to show my husband and let him know he needs to step up his game!!!” one woman commented.

Another joked, “Please add a disclaimer next time—coffee just shot out my nose and I think I may have peed a little. HILARIOUS!!!”

Tina later admitted to Scary Mommy that she never expected the overwhelming public response. “I’ve NEVER posted videos or photos of my kids public,” she said. “I only did it so the family could share it with their friends. I’m overwhelmed. I’ve received so many positive messages from people who’ve had hard knocks and said thank you for the two minutes of laughter.”

And for anyone wondering: yes—Steve and his daughters won that year’s Lip Sync battle. Frankly, how could they not?
