A prostitute goes to the doctor

[Groupie]

"doctor doctor i have 3 fannys"

"Nope no way not possible" he says

So the doctor has a look,and sure enough the hooker has 3 fannys,all in a row ... he tells her " im going to sew the two outer ones together and leave the middle one as it is".

"Doc, do you think that will help?"

"Well it'll stop you getting fuked left right and centre"

Hahaha.

I laughed (a bit), then thought, "This joke doesn't make sense." If the left and right are sewn up,but not the middle, it will stop her being f***ed left and right, but not centre.
Is there a better way of telling this joke?
