THEME:   "Oh, No!" title means there is a missing O which changes the meaning of a phrase   
GOOD ONES:     "$%*#& computer!"?   CRASH C(O)URSE   
Short anchor?   C(O)URT REPORTER [I thought it was Bob Costas]    
Spillane's inspiration?   MICKEY M(O)USE   
Like PETA members?   DOWN ON ALL F(O)URS   
Well-mannered sisters?   PROPER N(O)UNS   
Sugar daddy?   F(O)UNDING FATHER   
Way up   HIGH [as in "way up there"]   
Takedown expert?   STENO [I thought judo, etc.]

Batting organ   EYE   
Chain with popcorn   LOEWS [seems my granddaughter had one]   
One whose efforts were feudal   SERF [not "futile"]      
BTW:   Prior to A.D.   BCE [I really dislike this term, meaning "before the common era."  Was the previous era uncommon?  What then does A.D. stand for in this lexicon?  Silly anti-Christian jargon.]      
More than dull   DRY AS DUST [never really understood this simile --- here DRY is bad, but weather-wise and oenologically it's good --- so what makes dry a pejorative?]      
ESSA is only Italian and 
ETE only French.
