Punny Titles

What is it with cozy mysteries and their titles with puns?

For example:

Cockatiels at Seven by Donna Andrews - Andrews is one of the worst offenders in this area.

The Long Quiche Goodbye by Avery Aames

Scene of the Climb by Kate Dyer-Seely

Her Royal Spyness by Rhys Bowen

On What Grounds by Cleo Coyle - A coffee house mystery

Thyme of Death by Susan Wittig Albert

Grime and Punishment by Jill Churchill

State of the Onion by Julie Hyzy - Starring the White House chef.

Alpine for You by Maddy Hunter

Pleating for Mercy by Melissa Bourbon - About a dress maker

Feta Attraction by Susannah Hardy

Ladle to the Grave by Connie Archer

Claws for Concern by Miranda James - There is a cat on the cover.

Do you have any favorite punny mystery titles? I haven't read any of these books, so I couldn't tell you if they are good. The titles are hilarious, though.
