Sun Microsystems and Hewlett-Packard have always been, well, less than friends. As one journalist puts it, "'Mortal enemies' doesn't even begin to cover it." But the platform developer loves a good conference — as evidenced by JavaOne and Supernova. So, according to a tipster, they did the business equivalent of Scarlett Johanson borrowing lipstick from Lindsay Lohan.

Sun is so short of money now, that for a recent Sun Data Centre conference that they held in Melbourne, Australia, they had their event organiser seek external sponsorship. Someone from HP stepped up and sponsored a dinner or something, which resulted in the attached napkins being used throughout the whole conference. Apparently the Sun customers thought it was great, especially watching the Sun reps running around trying to pick up the napkins all day.
