Unable to keep track of an ever-mounting pile of federal items, President Clinton got a big box to put all the government's stuff in yesterday. 'It was getting really messy,' Clinton said. 'So I decided it was time to get it all off the floor.' According to Clinton, the box, made of sturdy, high-quality corrugated cardboard, will be used to hold many of the government's estimated 5.1 trillion belongings, which include 51 aircraft carriers, 296,000 staple removers and the tax records of every American citizen. 'That's a lot of stuff,' Clinton said. 'I just hope it all fits.'
