Okay, I can see - in a twisted way - how breaking in to your ex-girlfriend's house with a sword might seem like an exciting idea. (Still creepy and illegal, by the way, but I can see the appeal.) However, where this idea goes from kinda dumb to crazy stupid is when your ex-girlfriend's roommate is a sword collector. And he's home. So, several charges and an arm slice later, one guy has hopefully learned that lesson.
