I still recall the KLIF "Talk-Rock 1190" spoof promo we ran only ONCE at KLIF on the Kevin McCarthy show.
It lit up the switchboard and phone lines in the studio in such a way that poor Kev could only 'go with it' for about 40 minutes. Talking mostly with irate callers trying to argue and/or justify why this would happen to their favorite station.
Dan Bennett had to go on the air and assure KLIF's small, but loyal talk audience that we were not going to flip to a format that ran the hits of today underneath the talk of the town.
Here in Houston, we pulled a great one about 10 years ago, where all ther jocks flip-flopped shifts, time checks, etc, -we blamed it on the recent time change and a clock malfunction. Made for a great day of radio, and we kept it up from 5am until midnight.
Other than Day 1 for me on KILT, it is one of my most treasured tapes.
