McJ, that area is known as... well it needs a joke to explain.
A builder is contacted by the madame owner of a brothel to split one room into two (obviously to take on more clients at once).
He agrees to do the job cash-in-hand (under the table, no tax).
The dividing wall is erected and the builder is showing the finished work to the madame.
She then apologises that she has no money to pay him for his hard labour, instead offering him the goods of the house for free.
The builder is angry, but he agreed to do it off-the-books so what can he do?
He says ok. The madame brings in a few of her finest girls to pick from.
He grins, then declines them all in favour of the madame!
The madame is scared as she suspects the builder of plotting something, so offers the 3 girls simultaneously.
He now has a beaming smile and declines in favour of the madame again.
Realising she is now on the back foot she must accept his decision.
She strips down to prepare, lies down on a table, and the builder suddenly inserts a finger and thumb into her snatch and AAARRSE!!.
"GIVE ME MY MONEY OR I WILL RIP OUT YOUR DIVIDING-WALL!!!!!!!"
