Sources said Tuesday that Bruce Garver, a 42-year-old assembly line foreman at the Ford Motor Company's Dearborn, MI, plant, is giving serious consideration to asking a cute welding robot he works with out on a date. 'She's not only pretty, but I've never seen anyone so committed to their job,' said Garver, who said he'd asked around and learned that no one recalled the DX 700 spot welder ever mentioning a boyfriend. 'I'd never want to interfere with that, of course, but I bet she gets lonely sometimes. I know I do.' At press time, Garver had still not approached the 1,900-pound robot, reportedly convinced that she was way out of his league.
