Sorry for off topic tangent here, I've heard reference to kids doing this while watching
Dr. Who. Especially when the Daleks and other nasties came on screen. So, this was actually a thing? Kids did this?
I ask because doing this never occurred to me. Our couches were either up against a wall or had a large roll-top desk behind it that my dad used. So, no chance to duck behind the couch or any other furniture
. Would have been nice during a few creepy episodes of
The Twilight Zone or
The Outer Limits.
Believe the reference I first heard it from years ago was on the extremely funny British sitcom
Coupling. One of the main characters, Steve, mentioned hiding behind sofa as a kid and
Dr Who.
