Whether it's been five years or five minutes since you've seen "Jurassic Park," there's no way you've forgotten John Williams' iconic theme for the movies. It's crammed somewhere into a shadowy corner of your brain, just waiting for its big moment. And if you're Chris Pratt, star of the upcoming sequel "Jurassic World," then you've made up your own words to it.

Pratt was kind enough to sing his version of the classic score for us, complete with homegrown lyrics. Pratt said that he and his cast mates couldn't help but hum the theme on set.

"The score is so beautiful," Pratt said.

Then, of course, we had to get him to share his lyrics with us. Um, you think the dinosaurs are flipping out? We're flipping out.

Check out Pratt's version of the theme song, below.

"Jurassic World" hits theaters June 12.
