Would Infdiel Shake It?

A few days ago we posed this mysterious question …  WISI

A little history: Mike Firesmith ran across this salt and pepper shaker set and sent it to Infidel with a cryptic WISI? message.

Infidel promised to send in an image of it when it arrived.  Infi secured his “personal Hooter girl Ashley” to pose with the shaker set.  (She’s a LOT better looking than Infi anyway.)
