Yes, thanks to Brendan.
Super-quick solve but highly entertaining with many clues I enjoyed.
FOI 8, LOI also 14.
Thematic, and all the solutions in one direction are related. One key thematic goes in the other direction.
For personal reasons, my COD must be 1, closely followed by 11 and 17 neck and neck. Although rogissimo's choice of 21 is likely best from an objective standpoint: not only witty, but the key point relates to a couple of other clues in the grid. Also liked 13, 4, 5, 8, 19 and 25.
