The subject line refers to an old, old double-shot cheat that kids would try to pull when playing Hangman: they’d guess the letter “N”, and if it came up blank, immediately protest, “No, not N (nnnnn), I said M (mmmm)!”
This might work the first time, but that’s about it. Still, when this old gag crossed my path for the first time after many, many years while playing Hangman with my kids a few days ago*, it occurred to me to wonder if anybody has ever tried this gag on a game show like Wheel of Fortune. Does anybody know?
*Full disclosure: Actually I introduced them to this old, old double-shot cheat by attempting it myself when my head was in the gallows. And it worked, too!
