German U-boatmen had a unique sense of humor!

[**The following is from Otto Giese’s memoir *Shooting the War: The Memoir and Photographs of a U-boat Officer in World War II*.**] >After long hours under water the air would turn bad, 2.5 percent carbon dioxide. When the boat was surfacing, the pressure stabilized; before the conning tower hatch was even opened, one could see the bad air escaping. Boiling water in the messman’s pots would suddenly surge up and vaporize. We would get up and salute when this stinking mess passed out of the box. ________________________ **Source:** Giese, Otto, and James E.
