Nothing is life is free. Not lunch, not HBO, not even love. And definitely not hugs. So while a sign saying "Free Hugs" might seem like an altruistic act of simple kindness, you better be ready to tip the man carrying that sign, or face an assault.
At least, that can be the case in Times Square, where Jermaine Himmelstein was recently arrested (for the 17th time) and charged with robbery after punching a Canadian tourist in Times Square after she took him up on his offer of free hugs. So how did a friendly sign and the world's friendliest country turn into a felony?
