So shines a good deed in a weary world.

Cartoon of a robot with a human female. Human: "Robobert... do you think I'm pretty?". Robot: "Babe, you are a one zero". (It is ambiguous as to whether he said the word "ten" or "one zero"). Human: "Wait... in base ten or binary? Which one, Robobert?" The last panel shows the robot sweating and short circuiting.

Wow...
Google AI Overview that reads: The saying "don't drain the bathtub after midnight" is a superstition, and while there's no scientific basis for it, it's rooted in the idea of avoiding negative consequences or bad luck after that time. Some explanations point to the idea that midnight marks the transition to a new day, and draining the tub afterward could symbolically drain away good luck or energy for the day ahead. Others see it as a way to avoid disturbing the spirits that may be active at night. Ultimately, it's a belief passed down through culture and tradition, and its meaning is more about the symbolic act of avoiding negative energy than any literal effect.

Okay, this is both hilarious and a good example of why you should always treat AI output with a healthy does of skepticism...
Screenshot of AI output. It reads: The saying "two farts are worth more than a sack of potatoes" is a hyperbolic, humorous way of saying that something seemingly worthless or insignificant can be more valuable or valuable than a tangible possession, like a sack of potatoes. It highlights the subjective nature of value and the potential for things to be worth more than their material worth.

"the president defied a Supreme Court ruling to return a man mistakenly sent to a gulag... and spoke of sending Americans to foreign concentration camps.
This is the beginning of an American policy of state terror, and it has to be identified as such to be stopped"

Remember 22 years ago, when they renamed french fries "Freedom Fries" in the US House cafeterias?

And then a few years later, they realized how embarrassingly stupid that was and quietly changed it back?

I've been thinking about that lately for some reason...

I've been an a-ha fan for 40 years and only just now noticed that there's a dog on the cover.
The cover of a-ha's 1985 album "Hunting High and Low". A red box has been drawn in the lower-left corner to highlight that, among the people in the cover's black-and-white photo, there's a dog just laying on its side on a bench, chilling.
