<p>YOKO Ono still knows how to get a man to take his clothes off. Peter Jennings was interviewing Ono at last week's ArtWalk event for the Coalition for the Homeless when she somehow talked the news anchor into getting inside a giant black bag with her in front of 500 people at Cooper Union's Great Hall. A few moments later, both emerged with Jennings struggling to put his shirt back on and Ono's own garb disheveled.
