Though he doesn't know it, Eric actually isn't in the Hangovers at all. When Michael, Justin, and Colin went to tell him he didn't make the group, he turned into a Hulk-like creature out of anger, and threatened their lives. From then on, he just started showing up the rehearsals, and now remains "in the group" because everyone else fears the repercussions of telling him the harsh truth. Don't let the cute, humble exterior fool you--this kid is one crazy mother.
