Blue origin lost their first stage of new Glenn when it failed to land on the barge they had for it during a recent launch. And SpaceX lost the second stage of their starship when it broke apart also during a recent launch.

The joke is that you could take the second stage of new Glenn and put it on the first stage of starship. It ignores the fact though that the second stage of new Glenn is expendable and will not be returning to the surface of Earth in one piece.
