some of the dumbest book titles I've recently noted at work (the library)

Anthony Trollope is up there for the "classics:"

He Knew He Was Right
Can You Forgive Her?
Phineas Finn: the Irish Member
The Eustace Diamonds
Dr. Wortle's School


then there's Nora Roberts, a.k.a J.D. Robb:

Immortality in Death
Rapture in Death
Holiday in Death
Seduction in Death
Portrait in Death
Imitation in Death
Divided in Death

...you get the point.

Then there are the romance novels of Sandra Hill:

The Very Virile Viking
The Reluctant Viking
Truly, Madly Viking (I'm serious)
The Blue Viking
My Fair Viking
Here Comes Santa Claus

and lastly:

Kathy Reichs' Death du Jour
and my very favorite,
Deja Dead

Indeed.
