Bob is! Bob is a martial arts training device, or "Body Opponent Bag" that lives at House Party Headquarters. He's also the unofficial House Party mascot, often finding himself adorned in various festive attire. We have no idea how he came to our office, who brought him and what he does when he's not working. We also aren't certain why a company that throws parties would need a martial arts training device. Oooh, he's like our bouncer! Does your office have any odd mascots or items that have become the stuff of legend?
