When he's not trying to crop Jennifer Lawrence out of photos or jet-setting around Europe to promote his latest blockbuster, Chris Pratt is busy making time for his many fans. In addition to regularly visiting children's hospitals (sometimes even dressed as his Guardians of the Galaxy character), the down-to-earth dad has always made his love for the servicemen and servicewomen who protect our country known. On Monday, he made a fun visit to a Marine Corps Air Station in San Diego, where he had a blast hanging with both the soldiers and some adorable kids who were on the base to meet him. While there, Chris took a tour around an air hangar and struck a few poses with the jets, including a glorious flex of his insanely big bicep. Later on he gave everyone a private screening of his new movie, Passengers, which we're willing to bet was only slightly more entertaining than his hilarious bickering with J Law.
