Thanks for the explanation of 13A, Brendan. It wasn't my last one in, but I couldn't parse it for love nor money. A major lateral thinking failure on my part ... or possibly just desperation to get Seinfeld into a crossword somewhere.

Nope, it was just that I couldn't even see the stick, let alone get the wrong end of it. I saw 'Newman' in the clue and couldn't get past the chunky postman, even after the answer was in.
