A little Jewish Grandma is at the Florida coast with her little Jewish Grandson. The grandson is playing on the beach when a big wave comes and washes the kid out to sea. The lifeguards swim out, bring him back to shore, the paramedics work on him for a long time, pumping the water out, reviving him. They turn to the Jewish Grandma, and say, we saved your grandson. The little Jewish Grandma says, He had a hat!
