In the first story, the irony was that the men were in orbit around Vesta with no source of motive power and limited food and air but a year's supply of water. They find a way to use the water as a makeshift rocket in order to reach Vesta, and on the way down they make a toast: "Here's to the year's supply of water we used to have." At the end of this story, they change the toast to "Here's to the Silver Queen souvenirs we used to have."
