I read descriptions of a couple of newspaper ads years ago (in NY if I remember correctly).
One just said this is your last chance to send $2 to...and gave an address. It turned out the author wasn't prosecuted because they hadn't promised anything.
But the law was soon changed.
The other was a never fail cockroach trap. It was two rocks. Have the roach stand on one rock and smash it with the other rock.
I don't remember if they even tried to pursue that one.
And yet another very much needed laugh tonight. Thank you!
