Wheel must have NO type of screening
Wheel probably screens like other shows that are of sheer luck and not particularly skill or knowledge based. They like "bubbly" people, not really bright and bubbly, just bubbly. The Price is Right interviews people in line waiting to get into the studio audience for their contestants. They say the funner you appear to the interwiewer the better your chance. Granted I would probably nervous as well on a studio set vs my living room couch.
