No screen credit for Mr. Schtupman?

Mr. Schtupman is the European financier who bankrolls the son's takeover of Caesar's Palace. Curiously, no one has noticed his name, and he does not appear in the IMDB credits. Schtup is vulgar Yiddish for intercourse. Duh! I laughed so hard I choked on my rum and diet Dr. Pepper. Garson Kanin & Co. slipped this in and got away with it because the goyim audience in 1969 was ignorant...might as well name this character Prince Farqwad and delete the "r".
