THEME:   last word of phrase is an anagram of a mild curse: EGAD, DRAT, DARN, CRIPES   
GOOD ONES:     What the {theme} is in more ways than one  
 MINCEDOATHS [since the oaths are scrambled, they are in a way minced]   
Drop zone?   EARLOBE [ear drops]   
Checked for the last time?   MATED [in chess]         
BTW:   Aside from the usual tough Friday clues, we got some that were very tricky indeed:   
Lacking siblings for 
ONLY; Imitated for 
DID; "Put up your dukes, then!" for 
ITSON; Pen's mate for 
COB; Brief comment for 
IDO [more of an answer than a comment, though]; Injure, in a way for 
CLAW; Sum, sometimes for 
IAM [Latin]       
NLER is a non-word I'm beginning to hate.  Actually it would have been easy to avoid:      
62-A   BOWA [great Phillies shortstop]   
65-A   ILER [The Sopranos actor]   
68-A   GIRD [wrap]      
RATING: 
 
  
  
   Three grins = Loved it; Two grins = Enjoyed it; One grin = A bit bland for my taste; One teardrop = Not much fun
