Chicken farming.

Well not quite.

A woman walks into an accountant's office and tells him that she needs to file her taxes..

The accountant says, "Before we begin, I'll need to ask you a few questions." He gets her name, address, social security number, etc. and then asks, “What’s your occupation?"

"I'm a prostitute," she says.

The accountant is somewhat taken aback and says, " Let's try to rephrase that."

The woman says, "OK, I'm a high-end call girl".

"No, that still won't work. Try again."

They both think for a minute; then the woman says, "I'm an elite chicken farmer."

The accountant asks, "What does chicken farming have to do with being a prostitute?"

"Well, I raised a thousand cocks last year."

"Chicken Farmer it is."
