A man was shipwrecked on a remote island. Although he had plenty of food and water, there was nothing for him to do except play with himself. After many years, even that became so monotonous that he couldn't even get an erection. Now, completely without any happiness, his sanity began to slip away.
One morning, as he is lying on the beach, he thinks he sees a ship in the distance. He quickly starts a fire, then throws wet seaweed on top until smoke is billowing high in the air. The ship starts to come his way!
He gets all excited and thinks, "Finally! I'm going to be saved! The first thing I want is to take a long, hot shower. Then they're going to give me some clothes and I'm going to go upstairs and have a nice dinner. I will find a nice lady to dance with, then I will take to her cabin and we can kiss and I can fondle her body. She'll start to take off her clothes and she'll be wearing red silk panties!"
At this, he gets an erection. He slips his hand into his shorts, grabs his pecker, and yells, "Ha Ha Ha!! I fooled you! I lied about the ship!"
