How do they control themselves? Do they both control the whole body or does each control half? Would it be considered cheating if the one head slept with someone who's not the other's boyfriend(or girl)? Do they like Lego? Are they smarter than a 5th grader? And my axe. What happens when one of them gets drunk? What happens when they are both drinking, do they get drunk even faster? Which head throws up? Which one can feel physical pain?
