As what as a cricket?


This sounds like a reference to the illustrated children's book by Audrey Wood. The title is I'm As Quick As A Cricket. Here it is on Amazon:

The phrase "quick as a cricket" was almost certainly created for this book. It is not a common expression in English otherwise. All the occurrences of this expression in Google seem to be references to the book. If it were a standard expression in English, it would appear in some ordinary context and not just in reference to children's literature.
