Twenty seconds later, a comet sails up out of the flesh cosmos of the Bund and bounces on the wooden deck of the gunboat—a hell of a throw. Goto Dengo is showing off his follow-through. The projectile is a rock with a white streamer wrapped around it. Shaftoe runs over and snatches it. The streamer is one of those thousand-stitch headbands (supposedly; he’s taken a few off of unconscious Nips, but he’s never bothered to count the stitches) that they tie around their heads as a good-luck charm; it has a meatball in the center and some Nip writing to either side. He unties it from around the rock. In so doing he realizes, suddenly, that it’s not a rock after all; it is a hand grenade! But good old Goto Dengo was just joking—he didn’t pull the pin. A nice souvenir for Bobby Shaftoe.
