Students from Purdue University's Society of Professional Engineers won the 2008 Rube Goldberg contest with a device that requires 156 steps to assemble a burger. According to the team captain, 'We put 4,000 to 5,000 man-hours into this machine since September, and all the hard work has been well worth it.' That's a long time to wait for dinner."
