"Somebody change the channel," my father directed from vantage of his kick-back chair. There were no Lazy Boys in those days. Dad was slouched back into an overstuffed arm chair with his feet on the footstool in front of him.
'Somebody' means any kid within earshot and do it quick. If the lion's first growl doesn't get results then he doesn't growl twice. The next time he will ROAR!
If the ROAR doesn't get instant results then the cubs are going to get cuffed by either The King of the pride or the she-lion. Either way, it isn't pleasant. Being the eldest, and in interest of self preservation, I was usually first to launch myself toward the TV to twist the channel knob.
There were thirteen numbers and a UHF position on the knob but only three channels were broadcast. Figure that one out. Neither cable TV nor electronic remote controls ever existed in my father's lifetime.
With the channels that had no reception at all, you could twist on through them without much pause. With the strong-reception channels the human remote was required to pause until commanded to "change it again." Weak-reception channels also required The King's command before turning to the next channel on the first time around all of the channels. On the second pass the human remote understood not to tarry on the weak-reception channels lest he wants to suffer a ROAR.
“DO YOU NEED A CRANK ON THAT THING?”
Eventually, the commercials were over and The King would settle on one channel that had an old movie running. Within a few minutes, however, there was a good chance that The King was going to growl anyway.
“ARE YOU SURE THAT YOU DON’T WANT ME TO GET YOU A CRANK FOR THAT THING?”
