That's an interesting observation. I do agree that the shows you mention might have multiple Far Side-level gags in just a single episode. But as the other commenter argues, at the time it stood out. I'm perhaps a bit too young to have experienced The Far Side in its heyday, but I vividly remember the truly awful cartoons I'd read in the various newspapers I'd find in my day to day. Garfield was probably one of the better ones, and IMO Garfield is pretty shit, at least in hindsight. And yet I remember having Garfield collection books.
