Chris Pratt went on Conan to give a master class in how to (re)act when confronted with a cake or a dinosaur (or a dinosaur cake). “The worst thing you can do is overact,” he says. Then he turns into a face sensei and shows everybody his secret weapon for facial emoting. The result is very special, and if Pratt is not given a guest spot in Zoolander 2, there will probably be riots. SOS, Ben Stiller.
