Scientists who study congressional behavior reported Monday that some senators are capable of developing and using primitive legislative tools. 'We noticed about a month ago that an alpha senator and majority-leader silverback named 'Bill' had taken to banging his lectern with a hammer-like implement instead of using his fist or a leg of meat as the others do,' said congressional anthropologist Allison Weathers, author of Rotundas In The Mist, the acclaimed account of life among the great congressmen of the Potomac River region of the U.S. 'Since then we've seen multiple instances of tool use, such as small implements used for drafting and adjourning, as well as the rudiments of spoken language in the form of monosyllabic grunts such as 'aye' and 'nay,' common in group decision-making.'
