Oooh - famous one here in the Cactus patch, back in the 1970's...KIKX 580, Tucson:
Wikipedia: "A 1974 promotion gone wrong would ultimately be the catalyst for the station's demise. The promotion announced the kidnapping of one of the station's DJs, Gary Craig (real name Arthur Gopen), who at that time had taken over KIKX's morning show; the intention was that Craig would "disappear", call into the station from Miami, and then call in from various cities on his way back to Tucson, with lucky listeners who were able to identify the cities winning prizes."
Eight years of wrangling between the owner and the FCC via the courts on that one before the station shut down.
