Frank Sinatra, Sammy Davis Jr, and Dean Martin were walking along the beach when they saw a strange creature that had been washed ashore. Frank took a closer look and said, "What do you think, boys? Some weird kind of fish?"
Sammy took a closer look and said, "That's no fish. It doesn't have any fins. It's got to be a snake of some kind."
Dean took a closer look and said, "That, my friends, is neither a snake nor a fish. That's a moray."
