Zookeepers around the world have been copying Chris Pratt's velociraptor-taming moves from the film Jurassic World, with their own animals taking the part of the dinosaurs.
In the film a 'dinosaur researcher' confronts a group of velociraptors and calms them down using his arms.
Although they don't have their own dinosaurs, zookeepers have been trying out the technique with less-dangerous animals.
Tortoises, penguins, red pandas, and even rhinos have been included in the photos - which have now gone viral.
The people in these photos are professional zookeepers who are trained to work safely with animals. Don't try this yourselves.
