Sort:  

That doesn'r even broach the stories we got told at supper (like the one about him lancing a patient's penile pustule just to have it burst and have geriatric penis pus fly into his mouth, teeth and gums. We were 6.)

Currently I have acquired a taste for geriatric ear wax which seems to all too frequently splash back into my open mouth on ear syringing. Disconcerting when you smile and people ask if you have been eating toffee. An occupational risk but alas it is nearing an end.

You could try closing your mouth.

Great advice you saucey snot, never thought of that. But then I would never have the satisfaction of a belly full of wax.
