@mattyb yeah, I'm not sure if it counts so I've not bet a lot.
The Easter Egg was released for April Fools, and comparing what it does to what's listed on Wikipedia it's not too dissimilar. Strictly, some of what is listed on Wikipedia could also be categorised as easter eggs rather than jokes but I'll leave the line up to @AnneMundy.
@qqii the egg is fun, but it wasn't released for April Fools. Chrome v123 was released mid March. Not to mention it's clearly an Easter reference, not a prank/joke.
@DanHomerick the release notes says
To celebrate this year's April Fools' Day
I've also found the source commit, which contains this line:
const isAprilFools = (month === 4 && day === 1) || true; // TODO: show only on April fools
They made good on the TODO in this commit, with the code becoming
const isAprilFools = (month === 4 && (day === 1 || day === 2)); // Show only on April fools and the next day
short-fuse, this begins in a few hours [26 where I’m at]!
