Belatedly replying to OES's open call...

1. In the 70's I came up with the bon mot, "If you're not part of the solution, you're part of the precipitate."

2. In the late 80's/early 90's my eavesdropping skills were praised in the magazine Games.

3. Since moving to Australia in the 00's I have not made any of the mistakes that Americans typically make Down Under.

#1. Other people may also have come up with this, but I am at least one of its parents. It came to me in science class and I wrote it on a lot of graffiti spaces around Harvard Square. Much later I saw it had been used by others, for example the lovely/mad Britishgeeknewsweekly Need to Know at the foot of its original prospectus circa 1996. Also in the 90's my then husband used it in a written report for radio station WCRB-FM, although he attributed it to "Aleksandr Borodin, chemist and composer," which I guess he thought was more impressive than writing, "As my wife often says..."

2. During a live action role playing game (in New Jersey) our team included a guy that none of us knew who turned out to be an editor from Games working on an article. The GMs had kept him a secret because they knew that otherwise we would metagame his fool head off. Although I loved LARPGs I was almost dreadful at playing them, except for the eavesdropping, which is definitely my best thing, and metagaming (chronic, but didn't make up for lack of other basic skills), and ability to 'commit to my costume'.

3. This deserves a post of its own...
