Greetings all. I'm here to explain to you the connections and loopholes, or ins and outs of today's puzzle. Not that they need much explaining. The two revealers, clued as "Where work piles up" [IN]BOX and "Where finished work goes" [OUT]BOX tip us off to the fact that each theme answer has a literal [IN] and [OUT] box rebus square. Apt! Well, they tip us off to that fact once we get to the south easternmost part of the puzzle. I don't know if this happened to any of you, dear readers, but I entered FOUNTAINOFYOUTH (Goal for Ponce de Leon) right out of the gate, which, amazingly, fits in the same number of squares as the correct answer THEFOUNTA[IN]OFYO[OUT]H. Who'dda thunk? It's funny what fits when you don't realize there's a rebus. The same thing happened to me at 33D where I entered "blankly" for "One way to stare" instead of the correct answer [IN]TENTLY. My favorite theme answer was FROTH[IN]GATTHEM[OUT]H (Incensed). It's crazy good. :)
"Give the silent treatment?" (MIME) - what happens if you give a mime the silent treatment?
"Um, don't look now, but ..." (AHEM) - I enjoyed the scene this clue conjured up.
"The end of mathematics?" (QED) - I bet Huygens liked this one, if he is still out there puzzling.
"Middle of a puzzle?" (ZEES) - this self referential clue didn't fool me for a minute.
"Cash cache, for short" (ATM) - fun clue for an old chestnut.
And my personal favorite:
"John of Cambridge" (LOO) - ha!
URSI, LLCS, PSY, and AKC didn't AMAZE, but I do appreciate the fact that Mr. Eaton-Salners kept his clue for SHH librarian-free!
