"Eh? That kitten -- falling off a ledge--! They say a cat always lands on its feet -- but I'll make sure it has a 'soft' landing!"
In the Silver Age, storylines weren't "decompressed". Nowadays, it takes a six issue arc to catch a purse-snatcher running down the street, because during the chase you have to recount the incident's relevance to your origin story, argue on the phone with another member of your team, question your role in the larger superhero community, have conflict with either Superman or Aquaman or both, then muse on your complex relationship with the local authority figures.
In the Silver Age, you defeated other-dimensional world-conquerors, their planet-shattering weapons, & their slavering hordes in 11 or 12 pages (not counting splash panel), with enough time left for a panel or two of snappy repartee with your sidekick/girlfriend/comic relief character. Yes, in that happy era, heroes even made time in their schedules to save falling cats that probably didn't need saving.
In this case, so plentiful were heroes, in fact, that another hero rescued the cat first.
Who made the above speech and who rescued the cat instead of just talking about it...?
