The idea for that show came from a promotional stunt by a Los Angeles radio station involving doves. While waiting for the signal to release the doves from the roof, a couple of employees indulged in quite a bit of herb while waiting in a stairwell.....with the caged birds. When it came time to open the cages, the birds were whacked and refused to leave. So the spaced employees tossed them out...off the roof...they did not fly.
