The Warren William way!
First and most crucial is...you MUST wear a bejeweled turban! Without it, no one will believe you have psychic powers!
Second, you MUST learn how to gaze intently into the magic crystal!
Putting ones hands at the side of the required bejeweled turban will help focus your psychic powers! It will also help you to....
...better hear your other trusted assistant waiting under the stage as he speaks into the microphone and reads off whats written on the slips of paper that tumbled down through the trap door on your magic urn! If Allen Jenkins is unavailable (dont cry Ginger!) other good choices would be Frank McHugh, Guy Kibbee or Lyle Talbot, just make sure they lay off the sauce until after showtime!
With great power comes great responsibility! You must learn to focus while dolling out personal advice to your audience members, remember they are entrusting you with their lives!
It will be a tremendous help if your trusted assistant Allen Jenkins is able to procure a job as chaufeur to one of these high society couples!...not only will he be privvy to inside information about his employers that is vital to your psychic powers but he will also be able to gather info from other chaffeurs!
But again, none of this will matter if you dont wear the Turban!!!!
