The question that divided social media over the week also seemed to wreak havoc on "The Tonight Show" — or at least on the mind of its host.
“I apologize if I’m in a weird mood tonight," Jimmy Fallon said in his opening monologue Friday night. "I just lost all my friends over the color of a dress."
That would be #TheDress, which was so bafflingly polychromatic that it spawned a contentious debate (blue and black? white and gold?) and more than a few jokes.
“I think somebody should ask Obama, our country’s first gold president," he said.
“It’s gold history month,” quipped Fallon’s announcer, Steve Higgins.
Fallon wrestled with the question again in his weekly "Thank-You Notes" bit.
“Thank you, anonymous thief who stole Lupita Nyong’o’s $150,000 dress — or as the rest of the world calls it, not the dress we care about right now,” Fallon said. “It wasn’t blue and black, that’s all I’m saying.”
And when Fallon thanked the Cleveland Browns for introducing a new logo that's virtually identical to their old one ("more importantly: still not brown”), he nearly gave up on the question altogether.
“I don’t know what color anything is anymore," he said, before bursting into an impromptu “West Side Story”-styled song-and-dance number in the studio. (“Is it black and blue?! No it’s white and gold!”)
Comediennes Abbi Jacobson and Ilana Glazer, whose Comedy Central show "Broad City" is in its second season, visited "Tonight" to play a game of "Truth or Truth" with Fallon.
“Have you ever stolen anything?" Jacobson cooly asked Fallon.
“No,” Fallon deadpanned. “Just a couple of TVs.”
Besides trying to eke out gossipy details from each other's pasts, the guests and the host tried to stay as straight-faced as possible — and make the others crack up with hilariously over-the-top renditions of "truth or truth?"
Josh Hutcherson — known for his role as Peeta Mellark in "The Hunger Games" movies — also stopped by the studio to talk about his role in Ron Howard's upcoming project, "The Trailer." Naturally, Fallon asked him about his Twitter account.
“You can drunk-text, right?" Hutcherson said. "If you drunk-tweet, it’s like 2.1 million times worse. It can take 12 years to build a career, and you can ruin it in 140 characters or less.”
