You know, just like the rest of us. The viral prank team that previously brought us that [mutant spider dog video](https://www.youtube.com/watch?v=YoB8t0B4jx4 "undefined") decided to build some very realistic-looking dinosaur costumes and then attempt to prank Pratt, who really did seem to fall for it. (Unless he’s just always acting, all the time.) Naturally, Pratt reacts to the dinosaur ambush with a lot of cursing, but also manages to remain totally charming. Then he just gets confused, asking, “What is this? Who are you?” Then he makes friends with the pranksters. ### See Celebrities and Their Lego Figures  Chris Pratt: Owen Grady Universal; Lego  Chris Pratt: Star Lord Disney/Marvel; Lego  Zoe Saldana: Gamora Disney/Marvel; Lego  Dave Bautista: Drax Disney/Marvel; Lego  Robert Downey Jr.: Iron Man Disney/Marvel; Lego  Chris Evans: Captain America Disney/Marvel; Lego  Chris Hemsworth: Thor Disney/Marvel; Lego  Scarlett Johansson: Black Widow Disney/Marvel; Lego  Jeremy Renner: Hawkeye Disney/Marvel; Lego  Mark Ruffalo: Hulk Disney/Marvel; Lego  Paul Bettany: Vision Disney/Marvel; Lego  Elizabeth Olsen: Scarlet Witch Disney/Marvel; Lego  Aaron Taylor-Johnson: Quicksilver Disney/Marvel; Lego  Cobie Smulders: Agent Maria Hill Disney/Marvel; Lego  Tom Hiddleston: Loki Disney/Marvel; Lego  Samuel L.
