Philip sends in this puzzler
Wow, the last two Sundays were on the holidays, so there were a lot of LOLs people saw but we didn’t have the right place to post yet. And now …
A bit of synchronicity in my GoComics feed suits this post to a T.
Yep, that should have more cat-appeal than pizza.
And can’t let it go without a last-minute Zack!
This comic is from 1965, but showed up today at GoComics recycling of old B.C. comics. There are a lot of possibilities related to Janus being two faced, but do any of them come together as a gag?
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”.
Well, sure. I guess no one who could move snow with a magic wand would bother shoveling snow. But what’s the joke?
Actually, now that I think about it, I don’t understand why he was bothering to shovel snow before.
