The 21-second delay won't be the only thing that's different when Dom Imus returns to the air December 3rd on WABC. According to Bo Dietl, a former NYPD detective and frequent Imus guest, who was speaking on a local cable channel Saturday morning, Mr. Imus will appear with a co-host for the first time in his career. The Post advises Mr. Imus to ape fellow shock-jock Howard Stern by picking an African-American woman.
