Title: JW picked this one as title and reveal- OY VEY.

The exasperation  that causes people to use this expression, in this puzzle is the placement of OY in various known clauses and each groan inducing result. The themers are a bit inconsistent, with TOMBOY oddly clued and OYSTER breaking the second word. However that one is also my favorite image.  JW has a wonderful knack for making the puzzles challenging and interesting. Here we have the array of fill from all over the language. PHOTON,  MANILA,  YODELS,  NUBILE, TWO DAYS,  BUG EYED, GO TO CHURCH, and LOCAL PRIDE are the show.
