A broke but horny sailor is on shore leave from the navy...

so he finds the nearest brothel, goes up to the counter and says "I've only got $20$, what can I get for that?"

The old woman behind the counter says "Down the corridor, second door on the right.".

So he gives her the money, goes down the corridor and into the second door on the right. There on the table is a chicken, clucking away. So he thinks, 'fuck it, I've paid my money' and goes and fucks the chicken.

Next week, he's even more broke, and even hornier than last time so he goes back to the brothel and asks the woman at the counter "I've not got much but what can I get for $5 dollars?"

"Down the corridor, past the two doors on your right, up the stairs to the right and first door on your right." She says. So he goes down the corridor, past the two doors on his right, up the stairs and into the first door on the right.

Inside he sees 5 guys all crouched around something on the floor, wanking themselves off. He goes over and asks on of the guys, "What are you all looking at?"

The guy turns to him and shows him a hole in the floorboards. Through it he can see two gorgeous blonde lesbians going at it in the room below. "Wow, this is great! And I only paid $5!".

The other guy looks at him and says "Well you should have been here last week, there was a bloke fucking a chicken!".
