From Andréa, who points out for the synchronicity inspectors that although the Knight Life is a rerun or classic, its appearance on GoComics was 2022/11/08, same as the Candorville. The Candorville is a pretty good LOL at the end, too, despite edging up kinda near to partisan politics.
(Post-posting edit: As noted in comments, the following was the intended Knight Life, which actually uses the phrase “I can’t believe”.)
And for some additional fun on the “Can’t believe it” topic, Andréa also sends a link for this scene from The Vicar of Dibley. Impressive memory and facility from Emma Chambers, playing Alice.
