That will bring some skeletons crawling out of the woodwork

This is a delightful mixture of “skeletons in the closet” (secrets) and “crawling out of the woodwork” (secrets coming out in the open).  The confusion lies in the two phrases referring to secrets and exposing them.   I heard this in a conversation but I cannot reveal the source as I was sworn to secrecy.  We can’t have these malaphors crawling out of the woodwork, can we?
