Buckle up for the sweetest ride And prepare to have your mind blown wide When worlds collide Cavey: When worlds collide it's a curious thing Bet you've never heard a robot and a caveman sing In his metal chest are some working parts How is that different from my beating heart? Robot: I'm from the future... Cavey: ...And I'm from the past Robot: But that don't mean this friendship wasn't built to last Cavey: He was made in a lab and I was born in a cave So let me hear you holler for this inter-era rave! Robot: You... you... you... you can run... Cavey: But you can't hide! Robot: When... when worlds collide
