I can’t put my tongue on it

A girl was asked what gift she wanted for Christmas.  She couldn’t remember the name of the toy, and uttered this congruent conflation of “can’t put my finger on it” and “on the tip of my tongue”, both meaning something one can’t quite recall.   Fingers have tips so perhaps that is what led to the speaker’s confusion.  Or maybe she had watched too many reruns of the movie “A Christmas Story”.  A big thanks to Hannah Evanuik for overhearing this one!
