Old Knife in the skull

Drank some Old German beer last night, woke up this morning and it felt like I had been drinking something that should've had a more fitting name, like "Old Mugging", "Old Hangover', or "Old Knife in the Skull." Don't get me wrong, this stuff was great going down, well maybe not great but ok, or different, definitely drinkable.... But the next day, watch out. Prepare yourself if you ever come across this stuff, it goes down pretty smooth, but that knife that is sunk deep, deep into your skull the next morning is, well, unpleasant and pretty hard to remove.
