For once, some good news! Late last night, a friend sent me a link to this fiendishly frustrating puzzle, which looks easier than it is. The idea is to jump over each ball until all the balls but one are eliminated, and the best I could do was only to get it down to two remaining balls.

My sleepy brain was confounded by repeated attempts, and even though I was sensible enough to give up rather than lose sleep, it did little for my mood.

Finally, this morning I tried again after I'd finished my first post and second cup of coffee. It didn't take very long. (Got it on the third try.)

I humbly offer this screenshot as proof:

Believe it or nuts! (I think that's 1960s Mad Magazine vintage....)

BTW, I think sending this to anyone is a horrible thing to do -- and it should never be sent to a friend. I'm only posting it here because I know that there are some people reading who don't like me.
