“Jurassic Parks and Recreation” is a mashup by Thanks Mom Productions that combines the trailer for the upcoming film Jurassic World starring Chris Pratt with clips of Pratt as his Parks and Recreation character Andy Dwyer. The mashup creates the narrative that Andy gets transferred from the parks department in Pawnee, Indiana to the dinosaur theme park, where he is forced to deal with the chaos that ensues when a genetically modified dinosaur escapes.
For comparison, here is the original Andy Dwyer-free version of the Jurassic World trailer.
