It's Called A Double Entendre

I saw this coffee cup at a home decor store owned by very religious people (no, not that one).

This was sitting amid cherubs, crucifixes, and numerous frames containing variations on "Bless This House".  You would think someone who has such strong beliefs would realize that the phrase "Plan B" might have more than one meaning.  Or that someone would have pointed it out to them.  What I like best about this item is which words are emphasized.
