 This feature was partially a jab at radio hosts such as Laura Schlessinger (who offers psychological advice as "Dr. Laura" though her doctorate is actually in physiology, not psychology) who give advice on topics outside their range of expertise.However callers were instructed by the call screener to address Jillette as Doctor Penn, and were invariably corrected by Jillette.In one show Patrick can be heard yelling into the studio "it's Doctor Penn!"
