An unexpected personnel switch

Although I've never cared for the concept of April Fools' Day, I thought two radio stations pulled a good stunt on April 1 years ago.  The KMJM morning team switched places with KPNT's morning team and did each other's radio shows.  You wouldn't typically expect an alt-rock morning crew to do mornings on an R&B station and vice versa, so I thought the switch worked.  That's what a good April 1 radio stunt should be--one in which no one gets hurt.
