Appearing on MTV to debut an exclusive clip of the forthcoming new Jurassic Park sequel, which hits theaters June 12, Pratt came up with lyrics to the John Williams score, and what he came up with cuts right to heart of the series. “It’s Jurassic Park / It’s Jurassic Park / And the dinosaurs will flip out and eat someone / RUN!” Yep, that’s Jurassic Park, pretty much. That exclusive clip premieres Wednesday night at 11 p.m. ET on MTV. What Makes Chris Pratt So Funny?
