So there is this guy who thinks his wife is cheating on him, so one night he waits for her to leave then follows her in a taxi, only to find she is working in a brothel.

So he says to the taxi driver " do you want to make $100 " sure says the driver what do I have to do. 

Just go in to the brothel and grab my wife put her in the back here with me and take us home .

So the cabbie goes in and a couple of minuets later out he comes with a woman kicking , bitring , punching, screaming and fighting all the way to the cab. 

The cabbie opens the door and says here hold her, the guy looks at the woman and says this isnt my wife !

The cabbie says I know she's my wife, I'm going back in for yours.
