(NEWSER) – You didn't park a Smart car in San Francisco this weekend ... right? Well, four were flipped over between last night and this morning, apparently by a small group wearing hooded sweatshirts, NBC Bay Area reports. "They looked like they were up to no good," said an eyewitness who spotted the hoodie gang around a Smart car. "And sure enough, they huddled around it and lifted it up." How did the undersized vehicles look when flipped? "Like they are dachshunds sitting up on their hind legs."
