Last week, Jimmy Kimmel Live brought back its recurring feature Mash-Up Monday, getting country stars Lady Antebellum to share the stage with Bell Biv DeVoe and calling the result, naturally, Lady AnteBell Biv DeVoe. And last night, they brought back a couple of different generations of power-pop. New wave icons the Go-Go’s, who finished their farewell tour last year, returned to share the stage with YouTube stars OK Go. The resulting supergroup, the OK Go-Go’s, fused the Go-Go’s’ immortal 1981 classic “Our Lips Are Sealed” with OK Go’s 2005 viral hit “Here It Goes Again.” (They did not, sadly, bring the treadmills back out.) Watch the performance below.

There you have it: Indisputable scientific proof that “Our Lips Are Sealed” is a much, much better song than “Here It Goes Again.”
