witz
I am always disturbed by the amount of grease my face leaves on the phone and so: is there any wonder that the phone side of my face sports some nearly calcified, unburstable, leftover sebaceous cyst of which a nine-year-old German girl, after touching it, once asked: "Was ist das?"
Had I had my wits about me, I might have responded -- but also might not have and anyway, I so rarely have any German wits.
