Joe goes down to the docks...(long) ... to look for a job. He sees three old sailors sitting on a bench in front of a large ship, having a conversation. As Joe walks past to them, he hears what they're saying. - Number four! says the first sailor, and the other two starts to laugh. - Number six! says the second one with a giggle, and the other two starts to laugh. Joe is a little bit confused, so he walks up to them and asks: - Hey! I heard what you were talking about, and I have to ask, what's so funny about some numbers? - Well, says the third sailor, we have been out on the sea for more than thirty years. By this time we all know each other very well, so we decided to put numbers on our jokes instead re-telling them every time. - That sounds a bit weird, says Joe. - Maybe, says the second sailor, why don't you try for yourself? - Okay then, number eightythree, Joe says. All three sailors start to laugh really hard, one of them even falls of the bench and can hardly breathe. - What was so funny about it? Joe asks. Still giggling, the first sailor answers: - Never heard that one before!
