While in international waters, a commercial fishing boat was taking on water. The Captain got on the radio, “May Day, May Day!”

In a few moments he heard a crackling response on his radio from another fishing boat, “June Day, June Day.” Then yet another fishing boat responded, “July Day, July Day.”

The First Mate said, “Captain, what do all these responses mean in international code?"

The Captain replied, “It means man the life boats.”
