"Three breasted hooker" joke

There's this man who's taking a walk around the red light district
until he passes a whorehouse with a blinking sign saying: "The
Hooker With Three Breasts...". The man get's just a little
interested and thinks "well... that could be a once in a lifetime
experience". So he goes in and walks up to the man behind the
counter. "I'd like to see the hooker with the three breasts" he
says.
"Are you sure you can afford that... It'll cost you a thousand
dollars" the pimp replies. But, the man is too exited, pull's his
wallet and pays him the money. So, he's taken up three stairs to a
little room in the back of the house and when he opens the room...
there she is. The room is dark but as he comes closer he sees it...
three breasts! And so the man absolutely has the night of his life.
The next day the man walks past that same whorehouse and thinking of
the night before and the time he had, he goes in and pays the pimp
another thousand dollars. Again, he goes up three stairs to that
little dark room in the back of the house. And as the day before,
she lies there waiting.
But, as he walks up to the hooker, he sees that something is
wrong... "Hey! You had three breasts yesterday..." he says after
which she smiles and says "What did you expect honey... you can only
suck out a boil like that once!".
