NSFW: What's the dirtiest joke you know?

A navy man found himself in Shanghai, China without any money except for a dollar. Having the urge after so many months at sea he decided to go check out what adult entertainment was available.

He arrives at the first whorehouse he sees and asks the hostess if they had any adult entertainment available for a buck. The lady said sure they had something for a dollar. He gave the woman his one dollar and the woman gave him directions to room 69. When the navy guy entered room 69 there was nothing there but a bed and on top of the bed was a duck. So, he proceeded to have his way with the duck. Afterwards, he went back to the ship.

The following day, while he was walking the ship's hallway he found a quarter. He began to wonder what a quarter will get him at that whorehouse. So, he proceeded to go there and asked the hostess if they had anything for a quarter. The lady said sure, just go to room 70. When he entered the room he saw that there were people seated looking at peepholes into the adjacent room. After finding a vacant seat he proceeded to peer into the peep hole. After seeing a man in the other room having his way with a pig, the navy man exclaimed "This is totally disgusting". To that the man seated next to him said, "If you think that's disgusting, yesterday a man was fucking a duck".
