What's on Scrooge McDuck's beak (5-3)
I believe the answer is:
pince-nez
(Other definitions for pince-nez that I've seen before include "Pair of glasses with spring that clips on the nose and no sidepieces" , "Glasses clipped on to the nose" , "Pair of glasses that clip on the nose, with no side-pieces" , "Glasses fixed to nose" , "Pair of glasses that clip onto the nose" .)
