In Las Vegas Wednesday to talk with Justin Timberlake in advance of the pop star/actor's new movie, Matt Lauer had a guys' night out that could double as the trailer for "The Hangover 4."
The night began with the pair heading to the hotel elevator as Matt questioned one of Justin's accessories.
"You’re not gonna wear that, right?'' Matt said. "The man purse, you’re not wearing that. You’re just screwing with me."
"This is where I keep all my things,'' Timberlake said. "I get a lot of compliments on this. Besides, it’s not a man purse, it’s a satchel. Indiana Jones has one."
"Yeah, so does Al Roker,'' Matt said.
"And here's what's happening in your neck of the woods!" Timberlake replied.
The evening concluded with a Las Vegas tradition: an impromptu marriage. An Elvis impersonator confirmed Matt and Justin's man-crush by marrying them at the Classico Chapel.
"I can't believe we did this,'' a smiling Matt said while clutching flowers at the altar.
Justin then gave Matt a love tap on the backside as the happy couple walked down the aisle.
Back with his fellow anchors on TODAY Thursday, Matt reminisced about his wild night with Justin.
"I don’t remember any of it," he said, "but I lost a tooth.''
