You'll Find Out (1940)
Bela Lugosi: Prince Saliano
Prince Saliano : Presently I shall assume a state of trance, in which the outer mind merges with the astral portion of the human ego... the Spirit of Evil is trying to enter this room, but have no fear, the fires of death will guard us.
Kay Kyser : We have our business and you have your business.
Prince Saliano : [Affronted] Please do not refer to my calling as a business.
Kay Kyser : Oh, no offense, I just meant that everybody has to stick to his own racket.
Prince Saliano : [Insulted] Racket? Do you dare to suggest that the practice of the occult sciences is a racket?
'Prof. Karl Fenninger' : Do not merely suggest it, Mr. Kyser. Insist upon it.
