Silly question, but I’ll ask it anyway.

Darn it, all this time I was using clothes hangers to suspend my cables off the carpet.  Thank you @geoffkait 😊

Silly, no.
Clever, outside the box thinking, yes!

One can’t help wondering if the car would run better if the spark plug wires were all in the correct direction. Hmmmmm...

Just wondering, but can you make an interconnect with spark plug wire?

Why yes, MacGyver, yes you can. But it would be a lot more impressive to make one with pencil and paper. Graphite is conductive, you know. 

Oh wait! I know! What about Wrigley's chewing gum wrappers? Hey, this is fun!

why is or isn’t this done?

Uh, sound quality?

Or. Your could have said the reality of the situation- you just don’t know. Got it
