A new third engineer arrives in the engine room and is briefed by the 1st who tells him that most of the guys are stone deaf and have given up trying to scream out to each other. he then told him that if he wanted help with something he would have to think of hand signal.
The 3rd gets to work and quickly realizes he needs a handsaw so he waves at the 1st engineer and tries to use signs. He points to his eye, meaning, “I”, then at his knee, meaning, “need”, then he moves his hand back and forth, meaning, “handsaw”.
The 1st nods, then drops his pants and begins to masturbate.
The 3rd freaks out and runs down to the first yelling, '‘What the hell is wrong with you!?! Are you stupid or something? I was saying that I needed a handsaw!’'
The 1st looks at him and says, ‘‘I knew that. I was just trying to tell you that I was coming.’’
