Crossover Synchronicity

Thanks to Powers, who wrote:

Extra synchronic because they appear kitty-corner from each other in my Sunday paper.

And then there was Rubes from the very next day (Monday 20 June), which seemed to combine the two and made me wonder what was going on.

And just for a kicker, Monday’s Ziggy continued the theme: 

Editorial comment on “kitty-corner”: this Anglicism, also spelled “catercorner” and various other variations, apparently comes from the dots on a four in dice or cards being, well, kitty-corner from each other, plus the French word “quatre” for four, at one point also spelled “catre”. Given that the Brits have “centre” and the like, the mystery to me is why it’s not “catre-corner”.
