Mitt Romney may or may not know how to moonwalk. His hair isn’t made of chiseled African mahogany. And he loves to sing the “Taco! Burrito! What’s coming out of your Speedo?” song from Will Ferrell and Cheri Oteri’s Spartan cheerleaders SNL skit.

Those were just some of the revelations made Wednesday night by Romney’s sons in an appearance on Conan O’Brien’s late-night show on TBS.

The five Romney sons — Tagg (the eldest), Matt, Josh, Ben and Craig (the youngest) — appeared on the show on the eve of their dad’s highly anticipated speech to the National Association of Latino Elected and Appointed Officials (NALEO) conference in Orlando.

But politics was only a small part of the conversation. Instead, the sons — who, along with O’Brien, were sporting nametags — fielded questions on a range of topics, including their dad’s penchant for pranks.

Tagg related a story from Romney’s younger days, when the presumptive GOP nominee pulled a prank on a friend who was getting married.

“I remember a story from when he was in high school — I guess it was a little after high school,” Tagg Romney said. “His friend was getting married. And he found his way into the hotel room ahead of time, and the groom’s outfit was there. He took some pink nail polish and wrote on the first shoe, ‘H-E,’ on the sole, and on the next one, ‘L-P.’ And no one noticed it. It was a Catholic wedding, and when he knelt down to be blessed by the father, the word ‘HELP’ appeared.”

“That’s a very good prank,” O’Brien said.

Deadpanned Tagg: “I’m not sure if they’re still friends.”

Matt Romney told the tale of how he once pranked his own dad during the 2008 campaign by calling his cell phone and playing audio of Arnold Schwarzenegger’s voice. Romney, at that time competing for the GOP nod, had been angling for an endorsement from the then-California governor.

O’Brien had a prank of his own. After the commercial break, he re-introduced the Romney sons and then gestured to a trio of young men in sweater vests and tieless suits standing just offstage.

“Just in case anyone’s concerned we don’t have enough, we do have three extra Romneys on backup that can be brought in at any time,” O’Brien said. “That’s Tragg, Lagg and Bernie right there.”

During a series of true-or-false questions, O’Brien poked a little fun at Romney’s wealth.

“True or false,” he asked the sons. “Your dad went to college on a croquet scholarship.”

All five sons laughed but didn’t respond. “You need to tell people that’s not true!” O’Brien said after a few moments.

A few questions later, he took aim at Romney’s campaign-trail demeanor: “True or false: When your dad’s feeling under the weather, you call Dell Tech Support.”

And as for the presumptive GOP nominee’s fondness for the “Taco! Burrito” skit, Matt Romney divulged: “Any time you mentioned that word — ‘taco’ or ‘burrito’ — you knew my dad would chime in.”
