The Saturday Night Live alum wiggled and shimmied up and down mimicking, yes, a lava lamp. "I'm getting limber," he joked after his relatively lackluster dance, telling Centineo, "You'll definitely top that."
Game on. The heartthrob was tasked with Dirty Dancing When the Chaperone Ain't Looking. He seductively got low...while also peeking over his shoulder to make sure an imaginary adult wouldn't catch him. "Alright," said Fallon. "That's pretty good."
The duo continued to face off with moves including The All I know Is Musical Theater and Is this How You're Supposed to Grind. "Noah, you're clearly the better dancer," Fallon finally confessed. "Why even compete against each other when we can do one more dance together."
Their last hoorah: Making Eye Contact With Everyone But The Person You're Slow Dancing With. After all, haven't we all been there?
