Mrs GG and I usually solve one of the regular Sunday newspaper crosswords after breakfast. The crossword always has one answer consisting of two words beginning with known letters. For example, the last few editions have used the letters T and A. Nothing else is given about the answer except the numbers of letters of course. At breakfast today Mrs GG said "You know, we haven't had 'territorial army' as an answer yet." Guess what, there it was, the clue in question consisted of 11 and 4 letters and within minutes we'd solved the whole thing using Mrs GG's remarkable foresight.
I'm still recovering from the shock.
