Droll

   
GB commented that a quotation I read out to him was very droll. Now there's a word you don't hear often, I thought.

Droll - amusing in an odd way; whimsically humorous; waggish; dryly humorous.

Its first recorded use is said to be from around 1615–25 and its origin from the Middle French drolle -a pleasant rascal; or Middle Dutch drol - a fat little man.
