Slightly OT: There were pictures circulating on the web showing Natalie Portman allegedly getting her bare feet locked in stocks and tickled live on the David Letterman show. The pictures looked kind of doctored though. Was this a non-event, like Johnny Carson's oft-rumored rejoinder to Zsa Zsa Gabor's invitation to pet her pet cat?
