Greg is a man on a mission — a mission to redefine normal. Greg, who has Asperger's Syndrome, has a fanatical interest in classic movies and serial TV shows, which often leads to unusual conversations and behavior. "My name's not Captain Kirk, it's Greg. I just like the shirt." His 310-pound frame is often cloaked in costumes, ranging from a Confederate soldier's uniform to Captain Kirk from Star Trek. But Greg's charm is not rooted in his cursory knowledge of Star Trek; it's in his kind, gentle heart.
