A Polish gentleman living in Germany was shot in the head and being slightly sloshed at the time didn't even notice the bullet lodge in his skull.
The last 5 years has been a constant story of being totally pissed, swallowing paracetamol, aspirins and other pain killers (not only for his hang-overs) and in a moment of sobriety decided to visit the local German Quack, who just happened to be another Polish immigrant? (plenty of them in Germany too)
The Quack immediately diagnosed a slight lump in the Polish gentleman's head, took an x-ray and low and behold, discovered a bullet lodged in his skull.
Asked why the hell he didn't come earlier the Polish man answered:
"I don't remember a zing, only a very good party, ze bullet shooting and mein kopf ache uzzerwise, nichts, I need a vodka, Bitte."
The Quack removed the bullet and now the Pole has a hole in his Dummkopf. He is back under his favourite bridge with a very large bottle of cheap booze without the headaches, but still has a massive hang-over.
