A woman walks into the doctors office with a huge boil on her arse.
The doctor squeezes it, pushes it, and then looks at the hard white pus core. He says this is too big a job for me so he sends her to Gus the pus sucker.
The woman goes to Gus who looks at the bulging red, inflamed boil festering with pus and says "this is no problem" and he proceeds to press his lips to her arse and sucks out the pus and core of the boil.
Halfway through, the woman drops a mammoth fart. Gus stops what he's doing, looks up and says "You know lady, its people like you that make this job fucking disgusting."
