The Beach Walk, by Russell Conover

Sam was in paradise. He strolled the shore, listening to the crashing waves and smelling salt in the air. What could be better?

Then he noticed something. A fish, flopping on the shore, was stuck in a plastic soda can holder. Sam jogged over and freed the fish from the plastic ring.

“I am free! I cannot thank you enough! I will now grant you the wish of your choice.” The fish winked at Sam. His jaw dropped.

“Never thought I'd say this, but I've had too much time in the sun,” he muttered. “Madness is setting in.”
