On a cruise ship
A man is standing on deck, idly watching the water. On a nearby island, he spots somebody. He strains his eyes to see, and can make out that it is a very thin, dirty looking man with wild hair. He watches him jump up and down, wave, run along the beach and can even faintly make out that he man is yelling at the top of his lungs.
Intrigued, the Tourist turns to the Captain, who is standing nearby:
“So, what is up with that guy?”
The Captain shrugs.
“I dunno. He’s always this happy when we sail by.”
